Lines p and q are parallel and are cut by a transversal t. The angle formed on line p to the right of the transversal and above the line measures (4x+20)∘. The corresponding angle on line q in the same relative position measures (7x−55)∘.
a. (i) Find the value of x.
b. (ii) Determine the measure of each of the two corresponding angles.
c. (iii) State whether each of these angles is acute, right, or obtuse.
