Question

Angle ACB inscribed in arc ACB of circle with center
Dl Angle
ACB : 65° find mcarc ACB)​

Answer 1

Step-by-step explanation:

The Inscribed Angle Theorem : The measure of an inscribed angle is half the measure the arc intercepted by it.

Therefore , ∠ACB= half of Measure of arc AB

⇒Measure of arc AB = 2 x ∠ACB = 2 x 65° =130°

Since arcAB is minor arc and arc ACb is major arc and tyhe sum of minor and major arc is 360°.

⇒ Measure of Major arc = 360°- Minor arc

⇒ Measure of arc ACB = 360° -130°

=230°

Hence, m(arc ACB) =230°
