Answer:
8
Step-by-step explanation:
66 ÷ a = a + 2, anything that has R2 can also be rewritten to be plus 2. Then if you move 2 to the other side it becomes, (66 ÷ a) - 2 = a. Moving a to the other side will create this equation 66 - 2 = a x a. Therefore, 64 = a ^ 2. You just have to find the square root of 64 then.
Step-by-step explanation:
The perpendicular line has a slope that is the negative reciprocal of the other line's slope. So, in this case, the slope should be 1/3 (it's positive because a negative times a negative is a positive). This gets rid of all of the answers except for the last, I suppose.
