The relationship between angle 1 and 2 is alternate exterior angles.

When parallel lines are cross by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, linear angles, same side interior angles, alternate exterior angles, vertically opposite angles.

The parallel lines are line m and line l. The parallel lines l and m are cut by a transversal line and the angles formed are angle 1 and 2. This establish an angle relationship.

Therefore, the angle 1 and angle 2 forms an angle relationships.

Hence, the special relationship of angle 1 and 2 are alternate exterior angles.

The factors of 486 can be figured out by expressing it as products of its prime numbers, that is 486 = 2 × 3 × 3 × 3 × 3 × 3

Prime factorization is a way of expressing a number as a product of its prime factors. A prime number is a number that has exactly two factors, which includes 1 and the the number.

The first five prime numbers are 2, 3, 5, and 7. We shall divide the number 486 with prime numbers that are factors beginning with 2;

486/2 = 243

2 is not a factor of 243, the next prime number 3 is, so;

243/3 = 81

81/3 = 27

27/3 = 9

9/3 = 3

3/3 = 1

Therefore, the number 486 expressed as product of its prime factors is 486 = 2 × 3 × 3 × 3 × 3 × 3.

The given equation is [tex]r=\frac{1}{2}+cos\theta[/tex].

Therefore,

N + P = 90°

Let's find the angle N. The sum of angle M and N is 180 degrees. The angle M is given as 125 degrees. Therefore,

Staсia walked a total of 5 miles and 3,975 feet

Step-by-step explanation:

If two miles is 10,560 feet, then one mile is half that:
10,560 / 2 = 5280 feet.

Let's see how many whole miles fit into 30,375 feet?
30,375 // 5,280 = 5 miles.

Now we calculate the remainder:
30,375 - 5,280 * 5 = 30,375 - 26,400 = 3,975 feet.

So Staсia walked a total of 5 miles and 3,975 feet.

Tammy weekly pay as a baby sitter is 60 dollars.

The equation that can be used to find the weekly amount Tammy made baby sitting is  45 = 15 + 1 / 2x

Tammy receives a weekly pay from her job as a baby sitter. she spent half of this weeks pay at the bowling alley but earn an additional 15 dollars for walking the neighbours dog. She did not spend any additional money and finish the week with 45 dollars.

Tammy weekly pay as a baby sitter can be calculated as follows:

let

x = Tammy weekly pay as a baby sitter

She spent half of it on bowling alley = 1 / 2x

Therefore,

45 = 15 + 1 / 2x

45 - 15 = 1 / 2 x

30 = 1 / 2 x

cross multiply

x = 60 dollars

Therefore,

amount earned baby sitting = 60 dollars

The exact value of sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰ is -0.707.

The right expression is sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰.

We have to find the exact value of sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰.

The angles and sides of a right-angle triangle are measured using these trigonometric values. Cotangent, secant, and cosecant are the other three significant values in addition to sine, cosine, and tangent.

To solve this question we use the formula

sin(A+B) = sinA cosB + cosA sinB

If we compare the given expression by the formula, we get

A = 170⁰ and B = 55⁰

So the exact value of

sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰ = sin(170⁰ + 55⁰)

sin 170⁰ cos 55⁰ + cos 170⁰ sin 55⁰ = sin(225⁰)

The exact value of sin 170° cos 55° cos 170° sin 55° is startfraction startroot 3 endroot over 2 endfraction negative.

The exact value of sin 170° cos 55° cos 170° sin 55° can be calculated using the trigonometric identities.

First, the double angle identities for sine and cosine can be used to express the given expression as:

sin 170° cos 55° cos 170° sin 55° = (sin 170°)2 cos 55° (cos 170°)2 sin 55°

Now, applying the double angle identities for sine and cosine, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (1 + cos 340°) (1 + cos 110°)

Now, using the cosine addition formula, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (2 cos 170° cos 170°)

Now, applying the double angle identity for cosine, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (1 - (sin 170°)2)

Now, applying the Pythagorean identity, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (1 - (1 - (cos 170°)2))

Now, using the cosine addition formula, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (2 cos 170° cos 170° - 1)

Finally, applying the double angle identity for cosine, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (1 - (cos 340°)2)

Now, applying the Pythagorean identity, the given expression can be written as:

sin 170° cos 55° cos 170° sin 55° = (1 - cos 340°) (1 - cos 110°) (1 - (2 startfraction startroot 3 endroot over 2 endfraction)2)

From the information, at the animal rescue, 40% of the animals are dogs and 60% of the animals are cats. If the average age of the dogs is 9 months and the average age of the cats is 2 months.

To find the average age of all the animals, we need to calculate the weighted average of the ages of the dogs and cats, where the weights are the proportions of dogs and cats in the rescue.

The average age of all the animals is:

(0.4 * 9 months) + (0.6 * 2 months)

The total momentum between the objects during the collision is 210 kgm/s

Momentum is the product of the mass of an object and its velocity.

Since two objects are in motion towards each other. The first has a mass of 10 kg and a velocity of 7 m/s. The second object has a mass of 10 kg and a velocity of 14 m/s, from the law of conservation of momentum, the total momentum during the collision is the sum of their momenta.

So, the total momentum P = p + p' where

So, P = mv + m'v'

Given that

Substituting the values of the variables into the equation for total momentum, we have

P = mv + m'v'

P = 10 kg × 7 m/s + 10 kg × 14 m/s

Since then, the local real estate market has been in decline, and the property's value has dropped by 3.89% annually.

Each of Wayne's units rents for $495 a month, and he spends $26,400 a year on building maintenance.

Assume Wayne has consistently maintained a three-quarter occupancy rate at his apartment building.

Annual Revenue can be calculated as [Monthly Rent * Number of Rooms  Number of months * Three-quarters]

If we input the values, we have  = [495 * 20 * 12  (3/4)]

= $89100

Then the Total Profit can be calculated as the  [Annual Revenue - Annual Cost) * (Number of years)]

And this can be computed as :
