Can someone me with this? im stuck i don't get it.

Evaluate 8j -k+148j−k+14 when j=0.25j=0.25 and k=1k=1.

*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

Either enter an exact answer in terms of \piπ or use 3.143.14 for \piπ and enter your answer as a decimal.
