Constant proportionality

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with

*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

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
