The angle of elevation from a boat to the top of a cliff is 33. A sign is directly at the top of the cliff. The angle of elevation from the boat to the top of the sign is 37. If the sign is 40ft high, how far is the boat from the cliff. (The sign sits atop the cliff. So, the top of the cliff to the top of the sign is 40ft).

Step-by-step explanation:

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)
