Question

What’s is the value of x?

Answer 1

the answer is 12 since the sum of the two angles has to equal 180.

first you do

5x+5+115=180

combine like terms

5x+120=180

subtract 120

5x=60

then divide by 5

x=12

Answer 2

The answer is x=22
That’s because below the expression, 115 degrees labels the angle.
The angle with the expression doesn’t seem to be any different than the one below it.
Therefore, you would have to solve this problem to get x: (115/5-5=22)
