Answer:

m<A = 98.25

m<B = 81.75

m<C = 113

m<D = 113

m<E = 67

Explanation:

3x + 12 + 5x - 18 = 180

8x - 6 = 180

8x = 186

x = 23.25

3x + 12

3(23.25) + 12

81.75

5x - 18

5(23.25) - 18

98.25

6y - 5 + 10y - 7 = 180

16y - 12 = 180

16y = 192

y = 12

6y - 5

6(12) - 5

67

10y - 7

10(12) - 7

113
