You must know that the sum of the interior angles of a triangle is 180°. We also know we have 2 congruent sides.
To first find the value of n, we must subtract 132 from 180 which is 48. Then we know since the other two angles are equal, we can divide 48 by 2 to find that n=24°.

Next we know that one angle is 90°. So 90+24+(m+24)=180 . Solve for m.
