Answer this please.

the answer is 126 or B

Step-by-step explanation:

30 + 30= 60 so 60 + 12= 72 then 72 + 12= 84 after that you add 84 + 36 = 120 so finally you add 120 + 6=126 so 126 is your answer.

Brainliest if you liked the answer.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
