Answer 1

Explanation:

1) Vertically opposite angles are equal.

3a + 40 = - 6a + 94

3a = -6a + 94 - 40 {Subtract 40 from both sides}

3a = -6a + 54

3a + 6a = 54 {Add 6a to both sides}

9a = 54

a = 54/9

a = 6

-2b + 132 = -6b + 152

-2b = -6b + 152 - 132

-2b = -6b + 20

-2b + 6b = 20

4b = 20

b = 20/4

b= 5
