Through (2,-3) perpendecular 9y=x-18

y = -9x + 15

Step-by-step explanation:

9y = x - 18

y = 1/9x - 18/9

y = 1/9x - 2

Slope of the perpendicular line: -9 (negative reciprocal)

Point: (2, -3)

y-intercept: -3 - (-9)(2) = -3 - (-18) = -3+18 = 15

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
