asked • 12/07/23Finding degree measures in the triangle
Suppose that m<K = (5x +16) degrees and m<J = (4x + 25) degrees. Fine the degree measure of each angle in the triangle.

If it is an isosceles triangle, then the base angles are equal to each other. So, set the two expressions equal to each other and solve for x. Then, simply plug x back into each of the expressions to get the angle measures, which should be the same - if they aren't, check your algebra.

Thanks! But for some reason I keep getting decimals and idk if I am doing this correctly

You have 5x+16=4x+25; solve this and get x=9
when you plug in x, 5*9+16=61, both of the base angles are 61; vertex angle is 180-61-61=58
hope that helps
