I need help finding the angles. The answer Isn't even
mart [117]

The 3 inside angles of a triangle equal 180.

Add the 3 angles together to equal 180:


X + (5x-20) + 4x = 180

Simplify the left side by adding like terms:

10x-20 = 180

Add 20 to each side:

10x = 200

Divide both sides by 10:

x = 20


Angle A = x = 20

Angle B = 4X = 4(20) = 80

Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
