This triangle has an exterior angle labeled ∠A. All of the interior angles are labeled correctly. image e5f63f7bbab74b7f95dc5e8fc7f71331

Which statement about the exterior angle is correct?

A
It is 120° because 40°+80°=120°.

B
It is 140° because it is supplementary to 40°.

C
It is 50° because it is complementary to 40°.

D
It is 60° because 60°+40°=100°.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
