The third angle in an isosceles triangle is 56° more than twice as large as each of the two base angles. Find the measure of each angle.

2 answers

Let x = each of the other two angles, then the third angle = x + 56º

x + x + (x+56º) = 180º

Solve for x.
In re-reading your problem, third angle = 2x + 56º.

Sorry.
