Answer:
62
Step-by-step explanation:
First off, vertical angles are always congruent. Which means <A will be equal to <B.
m<A=8x+14
m<B=2x+50
8x+14=2x+50
So you want to get x alone so subtract 2x from each side.
6x+14=50
Since the variable is not alone you will also need to subtract 14 from both sides.
6x=36
You will need to divide both sides by 6
x=6
You now have x. You need angle B though so your not finished.
Plug 6 in for x.
2(6)+50
12+50
62
<B=62
