Question
what is the value of y?
p - 50°
p + 4°
y - 3°
p + 50°
y = □°
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, \(p + 50=(p - 50)+(p + 4)\).
Step2: Solve for \(p\)

Step3: Use the angle relationship
We know that \(y-3 + p+4=p + 50\) (by the exterior angle property or angle - sum in a different way of looking at the angles). Substitute \(p = 96\) into the equation \(y-3 + p+4=p + 50\).
