<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.

so

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

<h3>What are square roots?</h3>

Square roots are numbers multiplied by itself to give another number

<h3>How to determine the square root?</h3>

The equation is given as:

A = 121 ft²

Take the square root of both sides

√A = √121 ft²

Evaluate the square root

√A = 11 ft

Hence, the square root of the equation A = 121 ft² is √A = 11 ft
