<u>The question in English</u>

Observe the following triangles. Make sure they are similar.

we know that

If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar.

In the triangle ABC

Find the angle C

the sum of the internal angles of a triangle is equal to 180 degrees

A+B+C=180

solve for C

C=180-(A+B)-------> C=180-(50+57)

C=73°

angle C=angle R

angle A=angle P

therefore

<u>the answer is</u>

triangles ABC and PQR are similar

hichkok12 [17]

Answer:

9 units

Center is at (5, 0)

Step-by-step explanation:

The radius of the circle is equal to the square root of 81

$\sqrt{81}$ = ±9

Since the radius of a circle must be positive the answer is 9 units.

The center of the circle is at (5, 0)

A piece of green rope is being used to make a border around the outside of a sculpture that is in the shape of an equilateral tr

damaskus [11]

Answer:

The equivalent expressions are;

9x + 9

and

9(x + 1)

Step-by-step explanation:

Mathematically, we should understand that an equilateral triangle has all of its sides equal

So if one side is 3x+ 3, the other sides too measures same

Therefore, the length of the rope represents the perimeter of the triangle

This is obtainable by adding all the side lengths together

This will be;

3x + 3 + 3x + 3 + 3x + 3 = 9x + 9

This is also same as 9(x + 1)
