Question

solve for b. 68.5° 49.5° b b = ?°

Explanation:

Step1: Recall exterior - angle property

The exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.

Step2: Set up the equation

Let the exterior angle be the sum of the two non - adjacent interior angles. The exterior angle formed by the angles \(68.5^{\circ}\) and \(49.5^{\circ}\) is equal to \(b\). So \(b=68.5^{\circ}+ 49.5^{\circ}\).

Step3: Calculate the value of \(b\)

\(b = 118^{\circ}\)

Answer:

\(118\)
