Question

6. In Fig. 15.182, O is the centre of the circle. Find ZCBD.​

Answer 1

Answer:

Step-by-step explanation:

By degree measure theorem,

reflex∠AOC=2∠CBA

360°-100°=2∠CBA

260°=2∠CBA

260°÷2=∠CBA

∴∠CBA=130°

AD is a line.

∴∠CBA+∠CBD=180° (Linear pair)

⇒130°+∠CBD=180°

∠CBD=180°-130°=50°

∴∠CBD=50°
