Answer:
Angle C= 79 degrees
Angle X= 62 degrees
Yes, the two triangles are similar because all the angles are congruent. The requirement for two triangles to be similar is if two corresponding angles are equal.
Explanation:
A triangle is 180 degrees.
So adding the angles of triangle ABC, 62+39=101
180-101=79, so angle c is 79 degrees
Adding the angles of triangle XYZ, 39+79=118
180-118=62, so angle x is 62 degrees
