Question

What is the measure of ∠R?

Answer 1

23 degrees

Explanation:

90 + 67 = 157

180 - 157 = 23

there are always 180 degrees in triangles

Answer 2

<R = 23

Explanation:

The three angles of a triangle add to 180 degrees

<S + <T + < R = 180

We know < S = 90 and < T = 67

90 + 67 + R = 180

Combine like terms

157 + <R = 180

Subtract 157 from each side

157-157+ < R = 180-157

<R = 23
