Question

In the adjoining figure angle AOC 20 degree, Find angle BOC and angle COD. if angle are in AP.​

Answer 1

Given:

• <AOC=20°

To find:

• <COD
• <BOD

Solution:

By linear pair angle,

$\tt \: \qquad→ \: <AOC + <COD + <BOD=180° \\ \tt \: \qquad→ \: 20 + x + x = 180 \\ \tt \: \qquad→ \: 20 + 2x = 180 \\ \tt \: \qquad→ \: 2x = 180 - 20 \\ \tt \: \qquad→ \: 2x = 160 \\ \tt \: \qquad→ \: x = 80$

Measure of <COD and <BOD=80°
