Part a: how many solutions dose the pair of equations for lines a and b have? part b: what is the solution to the equations of lines a and b? explain your answer

Part A: The number of solutions for a set of linear equations (in this case only two of them, represented as two lines) is the number of points of intersection. For linear equations in 2-dimensions the only possible answers are zero, one and infinity. In this case it is clearly one.

Part B: By inspection, the point of intersection, and thus the solution to the system of equations, is (4,4).

r and t.

both are 64 degrees.

what i would say the best answer is a. 40.5
