Answer:
Step-by-step 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
