Question

what is the value of s?
s= ⚠ □ °

Explanation:

Step1: Find the adjacent angle of \(147^{\circ}\)

Since the sum of adjacent angles on a straight line is \(180^{\circ}\), the adjacent angle of \(147^{\circ}\) is \(180 - 147=33^{\circ}\)

Step2: Assume the other non - \(s\) angle is also \(33^{\circ}\) (due to the red marks indicating equal angles)

In a triangle, the sum of interior angles is \(180^{\circ}\). Let the two non - \(s\) angles be \(33^{\circ}\) each. Then \(s=180-(33 + 33)\)

$$s=180 - 66$$

Answer:

\(114\)
