Answer:

for 15 the answer is 61 and

16 the answer is 82

Step-by-step explanation:

First you need to know that these are vertically opposite angles and that the vertical opposite angles are always the same.

therefore in qn 15.

- the 125 degrees angle is vertically opposite to the 64 + x angle therefore we make an equation

64 + x = 125 (then minus 64 on both sides)

(64 - 64)+ x = 125 - 64

x = 125 - 64

x = 61

the same goes for qn 16.

85 + x = 167 (then minus 85 in both sides)

85 - 85 + x = 167 - 85

x = 167 - 85

x = 82
