Two distinct straight lines p and q are intersected by a transversal s. One of the interior angles on one side of s is (3x+15)∘ while the angle lying in the alternate interior position on the other side of s is (5x−25)∘.
a. (i) Form an equation in x using the information given above and solve it.
b. (ii) Using your result from part (i), determine whether lines p and q are parallel. State the reason for your conclusion.
c. (iii) Find the value of each of the two interior angles mentioned above.
