Lines p and q are parallel. Two different transversals r and s intersect them. Transversal r meets p at point A making an angle of (4x+12)∘ on the right side of r. Transversal s meets p at point B making an angle of (2x+48)∘ on the right side that corresponds to the angle at A. Determine the measure of the interior angle made by transversal s with line q on the left side of s.
a) 84∘
b) 108∘
c) 96∘
d) 92∘
