Question

Picture is shown !!!!

Answer 1

What is the length of PR?

d.9 is the length

The reason is because as we have 2 triangles and 21 is divided by 3 we have proof that 27/3=9.

Hope I helped!

Answer 2

You can use deductive reasoning for this. The angle measures are the same so they are similar triangles. This means that they are proportionate. Because the smaller left side is 1/3 the amount of the bigger one, you can assume that the other side follows the same pattern. The smaller side would be 1/3 the size of the bigger side and 1/3 of 27 is 9.
