Question

what is the value of x? x =

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: Apply the property

We know that \(x = 70^{\circ}+(180^{\circ}- 100^{\circ})\). First, calculate \(180 - 100=80^{\circ}\). Then \(x=70^{\circ}+80^{\circ}\).

Step3: Calculate the value of \(x\)

\(x = 150^{\circ}\)

Answer:

\(150\)
