Find the sum of 4x^{2} -4+6 and -7^{2} +3x+1

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

*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
