Hi there!
Angles in a triangle sum up to 180°, so:
180° = 110° + 5x° + 2x°
Simplify:
180° = 110° + 7x°
Subtract both sides by 110:
70° = 7x°
Divide both sides by 7:
x = 10°
Plug in to solve for the other angles:
5x = 5(10) = 50°
2x = 2(2) = 20°
110 + 2x + 5x = 180
110-110+7x=180-110
7x=70
7x/7= 70/7
x=10

Okay so combine like terms
10x-4x= 6x
2-8= -6
6x=-6
x= -1
Now to check:
10(-1)-2=4(-1)-8
-10-2=-4-8
-12=-12
