Two angles are congruent if and only if they have the same measures. If <1 and <2 are congruent angles, then you know m<1 = m<2 You are GIVEN expressions for the measures of <1 and <2. Substitute those into m<1 = m<2 Solve for x. Once you have a value for x, you can find m<1. And when you know what m<1 is, you can tell what KIND of angle it is.
