Answer:
angle b = 41
Explanation:
Start by writing out the equation it wants you to solve. If the question is asking fr angle b and angle b is equal to angle a you will have the equation:
3x-10=2x+7 where 3x-10 is angle b and 2x+7 is angle a
you are now going to solve for x, and to do that you want the x on only one side of the equation. Start by subtracting 2x-2x on the right side, which equals 0 and 3x-2x on the left side which equals 1x also written as just x. Whatever operation you do to one side, you do to the other. This leaves you with:
x-10=7
from here add -10+10 to get 0 and 7+10 to get 17 now you have:
x=17
now go back to the original equation:
B=3x-10 and substitute x with 17
B=3(17)-10
now solve the equation using your order of operations
B=3(17)-10
B=51-10
B=41
