Question

Angle ACD is an exterior angle of an equilateral triangle ABC. Find angle ACD.

Answer 1

Answer:

120°

Step-by-step explanation:

Consider ▷ABC

Since we know that a triangle has three sides, we only need to apply one Algorithm (formula) to find the answer.

The algorithm to find each exterior angle = 360°/n

(Where n = number of sides)

360°/n = 360°/3

= 120°

So, Each exterior angle is 120°
