WebOct 21, 2016 · 1 Answer. Base angles of an isoceles triangle are congruent. Therefore you get x 2 = 3 x + 10, which simplifies to x 2 − 3 x − 10 = 0 which after factoring yields the possibilities x = 5 or x = − 2, which both work. If you plug in x = 5, you will get that the base angles are both 25 degrees, which means the missing angle is 150 degrees ...
