Question

Find r, s, and t and then explain how you got your answer using at least two

vocabulary words (adjacent, complementary, supplementary, vertical).

Answer 1

r = 155°

s = 25°

t = 155°

Explanation:

25° is supplementary to <r. Therefore:

m<r + 25° = 180°

m<r = 180 - 25

m<r = 155°

25° and <s are vertical opposite angles. Vertical angles are congruent. Therefore, m<s = 25°

<r and <t are vertical opposite angles, therefore, they are congruent.

m<t = m<r = 155°
