Question

I really need someone to help me

The sum of the measures of the angles of any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, while the measure of angle C is 90 degrees larger than each of A and B. What are the measures of the three angles?
Angle a is
Angle b is
Angle C is

Answer 1

You know you're sum is 180
Let x represent the degree measure you don't know.
So:\[180=2x+(x+90)\]

Answer 2

A and B are the same so that's your 2x. And C is 90 degrees larger than Both A and B: x+90. Now all you have to do is solve for x
