Question

please help

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

Let x represent the measurement we don't know.
SO:\[180=2x+(x+90)\]
Since A and B are equal you get 2x
And C is 90 degrees bigger than either A or B so that's where you get (x+90)

Answer 2

\[180=2x+(x+90)\]
combine like terms\[180=3x+90\] now solve for x
