Answer: three angles of the triangle are 24 degrees, 84 degrees, and 72 degrees.

Step-by-step explanation:

Let's call the first angle x.

Then the second angle is x + 60.

And the third angle is 3x.

We know that the sum of the angles in a triangle is always 180 degrees.

We can use this information to set up the following equation:

x + x + 60 + 3x = 180

5x + 60 = 180

5x = 120

x = 24

So the first angle is 24 degrees.

The second angle is 24 + 60 = 84 degrees.

And the third angle is 3x = 3 * 24 = 72 degrees.

Therefore, the three angles of the triangle are 24 degrees, 84 degrees, and 72 degrees.

Okay so we need to find ABC, which is 2x, and we know the angles of a triangle all add up to 180.

To find angle C you must subtract the exterior angle from the total of the line, 180.

C = 180-145

C = 35

So now we have 3 elements, 95, 2x, and 35, and we know they all add up to 180 degrees.

95+35+2x=180

130+2x=180

50=2x

2x is the angle of ABC, so it's 50 degrees

The positive solution for the number is 6 as the expression will result to a quadratic equation.

A quadratic equation is a second-order polynomial equation in a single variable x in the form ax² + bx + c = 0. with a ≠ 0.

We Shall represent the unknown number with the letter x so that we have:

x² - 18 = 3x

x² - 3x - 18 = 0 {a quadratic equation}

x² + 3x - 6x - 18 = 0 {expand the middle term}

x(x + 3) -6(x + 3) = 0 {factor out x + 3}

(x - 6)(x + 3) = 0

x - 6 = 0 or x + 3 = 0

x = 6 or x = -3

we have two solutions for the quadratic equation and 6 is the positive solution

Therefore, the positive solution for the quadratic equation is 6

It needs to do that route I guess. But I don't understand the last question well.

The amount of time I spent tutoring from the tape diagram is 4 hours.

Let x represent one rectangle. Therefore from the tape diagram:

Amount of hours I spent tutoring = x + x = 2x

Amount of hours my friend spent tutoring = x + x + x + x = 4x

Since both me and my friend spent a total of 12 hours, hence:

2x + 4x = 12

6x = 12

Dividing through by 6:

x = 2 hours

Amount of hours I spent tutoring = 2x = 2(2) = 4 hours

The amount of time I tutor is 4 hours.

By factor decomposition and algebra properties, the number √180 is equal to 6√5.

In this problem we find an imperfect square root, that is, a square root whose root is an integer. However, we can simplify the expression by means of algebra properties and by redefining the number inside the root operator as a product of integers. Now we proceed to show the complete steps of the procedure:

First, decompose the number inside the root operator by factor decomposition:

√180 = √(2² · 3² · 5)

Second, simplify the resulting expression by algebra properties concerning roots:

√180 = √2² × √3² × √5

√180 = 2 × 3 × √5

√180 = 6√5

Therefore, the number √180 is equivalent by algebra properties and factor decomposition to 6√5.

Answer: To find the answer, I first understood that the first number is a product of two factors and the second number is the sum of those two factors.

So, I started by listing out all the factors of the first number which is 16. The factors of 16 are 1, 2, 4, 8, 16.

Then I looked for a pair of factors from the list whose product is 16 and sum is 10.

I found the pair (4, 6) which satisfies the condition.

So, I confirmed that 4 x 6 = 16 and 4 + 6 = 10.
