Answer:
AC = 6√3 in
Step-by-step explanation:
<h3>Finding the length of the chord:</h3>
Join OC. Now ΔAOC is an isosceles triangle as OA = OC =radius.
∠A = ∠C = 30.
∠A + ∠C + ∠AOC = 180 {angle sum property of traingle}
30 + 30 + ∠AOC = 180°
∠AOC = 180 -60
∠AOC = Ф = 120°
Find the length of radius using the bellow formula.

Ф = 120°
Arc length = 4π

Answer:
steps below
Step-by-step explanation:
√2 * sin(x+45°)
= √2 * (sinx cos45° + cosxsin45°)
= √2 * (sinx * √2/2 + cosx * √2/2 )
= (√2 * √2/2) (sinx + cosx)
= sinx + cosx
