Answer:
a = c = 85° and b = 95°
Step-by-step explanation:
b and 95° are vertically opposite angles and are congruent, then
b = 95°
a and 95° are adjacent angles on a straight line and sum to 180° , then
a + 95° = 180° ( subtract 95° from both sides )
a = 85°
a and c are vertically opposite and congruent , then
c = 85°
