The sum of the interior angles in a triangle = 180

There are three angles, 30, x, and x.
Since there are two x, you can therefore write this equation and solve for x.

180 = 2x + 30
150 = 2x
/2 /2
75 = x

Therefore the answer is C, 75.

Well since both of the angles are congruent we just need to do 180 - 30 = 150
150 / 2 = 75

(C) is the answer :D

p(x) = r(x) - c(x)

p(x) = 10x - (4x+15)

10x - 4x = 6x

The answer is C 6x - 15 because the negative is distributed into the positive 15 to make it a negative.
