Answer 1

Choices
18
72
36 radical 3
36 radical 2

Answer 2

It's an isosceles triangle because the two angles are the same. So RS = ST = 36. Now use pythagorus to solve for RT

Answer 3

In a 45-45-90 triangle, the two legs are congruent. This means ST = 36. You can use the Pythagorean theorem to get the hypotenuse.
36^2 + 36^2 = (RT)^2

Answer 4

36 radical 2

Answer 5

Right
