triangle CDE ~ triangle PQR. m angle C=13 degrees , m angle D=65 degrees what are the measures of angles P,Q and R?
Since triangle CDE ~ triangle PQR, the corresponding angles are congruent.
Therefore, the measure of angle P = 13 degrees (corresponding to angle C)
The measure of angle Q = 65 degrees (corresponding to angle D)
Therefore, the measure of angle R = 180 - (13 + 65) = 180 - 78 = 102 degrees.
