What’s the answer ? use the picture to see the problem

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer

y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?
