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
