Answer:x=13
Step-by-step explanation:
Since they are both corresponding angles you can create the equation
5x+21=86
Subtract 21 from each side
5x=65
Divide each side by 5
X=13
Here is what you have to do first, combine like terms. On the left side do x-3x (you can do 1x-3x because x is just 1 variable, so I can see why you put 1x instead of x). Then combine -3-1. Then add the x answer on the left side to the 2x on the other side then you can figure out the rest. The reason why I want you to figure out the rest is because I'm just helping you and you need to get the answer yourself.
13 is 10% of 130.
You want to multiply 13 x 10 = 130
