3 pieces times 20 degrees equals 60 degrees <span />
Answer:6
Step-by-step explanation:
Arc PQR measures 210°
An intercepted arc measures twice the intercepted angle. Here, the intercepted angle is ∠PSR. Hence:
Arc PQR = 2 * ∠PSR
1.) Compute for ∠PSR first. Opposite angles in a quadrilateral measures 180°. Hence:
∠PQR + ∠PSR = 180°
75° + ∠PSR = 180°
∠PSR = 180° - 75°
∠PSR = 105°
2.) Proceed with computing Arc PQR:
Arc PQR = 2 * ∠PSR
= 2 * 105°
= 210°
