The total is 90°. Set the equation

8x - 6 + 80 = 90

Simplify. Combine like terms

8x + 74 = 90

Isolate the x. Do the opposite of PEMDAS. What you do to one side, you do to the other

8x + 74 (-74) = 90 (-74)

8x = 16

8x/8 = 16/8

x = 2

2 is your answer for x

hope this helps

You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2
