From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:
Now, since interior angles of any triangle add up to 180 degrees, we have

By combining similar terms, we get

Then, x is given as

Therefore, the answer is x=90 degrees
Answer:
79
Step-by-step explanation:
63+48=101
180-101=79
6(4.5y - 12) = 9
(4.5y - 12) = 9/6
4.5y - 12 = 1.5
4.5y = 1.5 + 12
4.5y = 13.5
y = 13.5/4.5
y = 3
Answer:I think it would be y=2x-6
