Answer: s = 75
Step-by-step explanation: In this problem, we are given the triangle shown and asked to find the value of s.
To do this, we will use the Exterior Angle Theorem.
The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of its two remote interior angles.
So we can create the equation s + 44 = s + (s - 31).
Solving the equation from here, you should find that s = 75.
