Question

What is the value of x in triangle ABC?

Answer 1

x + 8 + 2x-8 + 3x-12 = 180

6x -12 = 180

6x = 192
x = 192/6
x = 32
 answer is C

Answer 2

The measures of the angles in a triangle add up to 180 degrees. Make the angles add up to 180 in an equation and solve for x.

(x + 8) + (3x - 12) + (2x - 8) = 180

Combine like terms.

6x - 12 = 180

Add 12 to both sides.

6x = 192

Divide both sides by 6.

x = 32

C) 32 is your answer.
