Answer:

A = 100

B = 50

C = 30

Step-by-step explanation:

You can make this equation to solve:

2x+x+x-20=180

4x-20=180

   +20  +20

4x=200

divide both sides by 4

200/4 = 50

x=50, B = x = 50

2x = 100 = A

x-20 = 30 = C

The measures of the angles of the triangle are

∠A = 100°

∠B = 50°

∠C = 30°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , ∠A = 2x

Similarly, the measure of angle C is 20° less than the measure of angle B. Therefore, we can write:

∠C = x - 20

The sum of the measures of the angles in a triangle is always 180°

∠A + ∠B + ∠C = 180

And , 2x + x + (x - 20) = 180

On simplifying , we get

4x - 20 = 180°

Adding 20 on both sides , we get

4x = 200°

Divide by x on both sides , we get

x = 50°

So , measure of ∠A = 100° and the measure of ∠C = 30°

Hence , the angles of the triangle are solved

Answer:

(c)

Step-by-step explanation:

This is because,

Triangle ABC = Triangle XYZ

So,

AB = XY

BC = YZ

AC = XZ

The True statement is

AB / XY = BC / YZ = AC / XZ

Two triangles are said to be comparable if their two sides are in the same ratio as the two sides of another triangle and their two sides' angles inscribed in both triangles are equal.

We have,

ΔABC and ΔXYZ are similar.

Now, if ΔABC and ΔXYZ are similar then

The ratio of the corresponding side are equal

AB / XY = BC / YZ = AC / XZ

and, the corresponding angles are congruent

<A = <X, <B = <Y, <C = <Z

Answer: 14 marbles

Step-by-step explanation: well nico had 54 marbles and 40% is with charlie so just subtract 54-40 and you'll get your answer

Nico had 140 marbles to begin with. After giving away 56, he would have 84 marbles left.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Now, we need to use some basic math.

Here, 56 marbles represent 40% of Nico's collection, then we can set up a proportion to find out how many marbles Nico had to begin with.

First, we'll set up the proportion:

56 / x = 40 / 100

Here, x represents the total number of marbles that Nico had before giving away 56.

Then, we get;

56 100 = 40 x

Multiplying both sides, we get:

5600 = 40x

x = 140

So, Nico had 140 marbles to begin with. After giving away 56, he would have 84 marbles left.

Answer:

You can't really answer (from what I think) if you don't know how much paper there is in a pack, but let's say there are 100 pieces of paper in a package and Aaron uses 18%, that would mean Aaron uses 18 pieces.

divide 18 by 100= 0.18 which can be converted to 18% [tex]\frac{18}{100}[/tex] 0.18

Answer:

96 inches squared or [tex]96in^{2}[/tex]

Step-by-step explanation:

So I'm assuming that the figure shown is the fragment that is left because it doesn't exactly say what it is.

The area of a rectangle is length times width, so to the area of the original manuscript is....

A=lw

A=20(12)

A=240

You get 20 from the question and 12 from the figure.

Next, you should find the area of the fragment that is left. I would split it up into two shapes, a triangle and recitable, since right now it's a weird looking shape. The area of a triangle is base time height divided by 2....

A=[tex]\frac{bh}{2}[/tex]

The base is 12 because 18-6=6 and the height is 12 because is the width of the original rectangle. (I suggest making a line in between fragment to spilt it into two shapes or even re-drawing it to see it more clearly.) Therefore plugging everything into the equation....

A=[tex]\frac{12(12)}{2}[/tex]

A=[tex]\frac{144}{2}[/tex]

A=72

Now to find the area of the rectangle of the fragment that is left over, use the the same equation from above that was used to find the area of a rectangle and just plug in the numbers 12 and 6 because you can use the number on the top and the number on the side of the figure

A=12(6)

A=72

The final step is to subtract the area of the smaller rectangle and triangle from the original manuscript

240-72-72=96

Therefore the answer is [tex]96in^{2}[/tex]. Hope this helps. : )
