Question

what is the value of c?
c + 40°
c - 32°
c = □°

Explanation:

Step1: Use the exterior angle theorem

The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles. So, \(c + 40^{\circ}=c+(c - 32^{\circ})\).

Step2: Solve the equation
