Explanation: Both triangles are similar polygons. In other words, they have corresponding angles. This means that the angles will stay the same even though the sizes of the two triangles differ. Since they have the same angles, angle N will also be 50 degrees just like angle Z. If we know that angle N is 50 degrees, and angle M is 88 degrees, then adding them together and subtracting it from 180 will get the answer since every triangle adds up to 180 degrees.
