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?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
