Question

Can someone help me

Answer 1

∠ BAD = 10°

Explanation:

The inscribed angle BAD is half the measure of the central angle BCD, then

∠ BAD =
`(1)/(2)` × 20° = 10°

Answer 2

10°

Explanation:

180-20 = 160

<BCA = 160°

AC=CB because its Radius

so the angle for <CBA and <BAD also the same

(180 - 160) ÷ 2 = <BAD

<BAD = 10°
