Question

3) ZACB is inscribed in arc ACB of a circle with centre O if
ZACB = 65°. Find m(arc ACB) =​

Answer 1

Answer:

m(arc ACB) = 130

Step-by-step explanation:

ZACB is inscribed in arc ACB.

ZACB = 65°

Therefore by Inscribed angle theorem.

ZACB = 1/2 x m(arc ACB)

65 = 1/2 x m(arc ACB)

m(arc ACB) = 65 x 2

m(arc ACB) = 130
