Answer:
See below ~
Explanation:
The total internal measure is 360°.
Finding ∠SPQ (clockwise):
Finding ∠SPQ (counterclockwise) :
Angles around a point sum to 360°
⇒ ∠SPT + ∠TPU + 86° + 60° + 154° = 360°
⇒ ∠SPT + ∠TPU = 60°
Therefore:
∠SPQ clockwise = ∠SPT + ∠TPU + 86°
= 60° + 86°
= 146°
∠SPQ anticlockwise = 60° + 154°
= 214°
