"The diagram shows a triangle ABC and the arc AB of a circle whose centre is C and whose radius is 24cm. The length of the side AB of the triangle is 32 cm. The size of the angle ACB is θ radians."
"Show that θ = 1.46 radians"
So i'm somehow supposed to *acquire 83 degrees from this and I cannot use both the sine and cosine rule. I've thought of *almost* everything with no success, how would you answer this?
