Angles are 72° , 72° & 36° SHAPE is a regular pentagon. The sides SH and PA are produced to meet at T.
Step-by-step explanation:
SHAPE is a regular pentagon.
=> Interior angle of Pentagon = (5 - 2) * 180/5 = 108°
The sides SH and PA are produced to meet at T
∠THA = 180° - 108° = 72°
∠TAH = 180° - 108° = 72°
∠THA + ∠TAH + ∠HTA = 180°
=> 72° + 72° + ∠HTA = 180°
=> ∠HTA = 36°
