Question

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 7878 degrees larger than each of a and
b. what are the measures of the three​ angles?

Answer 1

Im assuming that the difference is 78:-

2a + c = 180   ( Note 2a = a +b   because  we are given that a = b))
c   -  a  = 78    Subtract:-

3a  = 102
a = 34

So a=34, b=34 and c = 112  Answer.
