### Question

In the diagram, O is the centre of the circle and < PQR = 106$$^{\circ}$$, find the value of y.

A) 16

B) 37

C) 74

D) 127

### Explanation:

2y + Reflex angle = 360

Reflex angle = 360 - 2y

360 - 2y = 2(106)(angles at a centre = 2ce < of circum.)

360 - 212 = 2y

148 = 2y

y $$\frac{148}{2}$$

y = 74o

## Dicussion (1)

• 2y + Reflex angle = 360

Reflex angle = 360 - 2y

360 - 2y = 2(106)(angles at a centre = 2ce < of circum.)

360 - 212 = 2y

148 = 2y

y $$\frac{148}{2}$$

y = 74o
