Question

In ΔRST, ∠R = 85° and ∠S = 52°. Find ∠T.

Answer 1

43°

Explanation:

A triangle has a total angle of 180° and we can use it to find the answer.

The attachment is a visualization of the triangle.

In order to find angle T, we can use the triangle formula to find t.

`{180}^(o) = r + s + t`

By substituting r and s, we will get

`{180}^(o) = {85}^(o) + {52}^(o) + t`

Hence, we can find T, which is

`t = {180}^(o) - {85}^(o) - {52}^(o) = {43}^(o)`
