Answer:

a = 63

b = 117

c = 63

Step-by-step explanation:

The sum of interior angles in a triangle is = 180

so the measure of a:

85 + 32 + a = 180 add like terms

117 + a = 180 subtract 117 from both sides

a = 63

a and be are supplementary angles so their sum is equal to 180

180 - 63 = 117 is the b's value

since a and c are on a pair of parallel lines, their value must be equal therefore the value of c is also 63
