Question

ASAP!!!! What is the answer?

Answer 1

Answer:

A, B, C

Step-by-step explanation:

Since the sum of the angles in a triangle is $180^{\circ}$, you can set the equation $9x-7+7x-9+28-2x$. Simplifying gets $14x=168$. Dividing gets you $x = 12$. This is only x so you have to substitute 12 for x in the angles in the beginning to get $\angle{A}=101^{\circ}$, $\\\angle{B}=75^{\circ}$, $\\\angle{C}=4^{\circ}$
