Answer:
r = 155°
s = 25°
t = 155°
Step-by-step 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°
