Question

find unknown angles <p,<q and <r​

Answer 1

Step-by-step explanation:

let centre is X

OXD =90°(right angle )

let

CXD =180°

l40°+ 90°+AXC = 180°

130° + AXD =180°

AXD = 180°- 130°

AXD = 50°

Now

AXB = 180°

180° = 50°+ CXB

CXB = 180°- 50°

CXB = 130°

Now

CXD = 180°

180° = 130° + DXB

DXB = 180° - 130°

DXB = 50°
