Answer:
x=15
Step-by-step explanation:
See how the two angles come together to form a straight line? That means they add up to 180 degrees. So,
(6x+5)+(6x-5)=180
12x=180
x= 15
On following problems, they might ask you to calculate the actual angles. to do that, just solve for x and then plug in the value of x. in this problem, you would plug in 15 for x, so the one angle 6x+5 would be 6(15)+5=95 degrees and the other one is 6x-5 which would be 6(15)-5=85 degrees
