Question

Based on the measures

Answer 1

A circle is a curve sketched out by a point moving in a plane. The measure of the ∠ACB or θ is 50°.

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

In order to solve the problem, we need to draw a line segment AB. Since A is the center of the circle AC and AC both will be the radius of the triangle ΔABC. Since two sides of the triangle are equal, the measure of ∠ABC and ∠ACB will be equal therefore, we can write,

∠ACB + ∠ABC + ∠BAC = 180°

2∠ACB + 80° = 180°

∠ACB = 50°

Hence, the measure of the ∠ACB or θ is 50°.
