Two bird watchers position themselves at point A (the beach) and point C (the shed) which are 111 feet apart. The both spot a rare bird at point B using their binoculars. If they see the bird at 94º and 46º respectively, how far is the bird from the bird watcher in the shed (point C) (to the nearest foot). *

120 ft

Step-by-step explanation:

Given

Beach(A) and Shed (C) is feet apart

If Two bird watchers set then at A and C and observe a bird at and  

Using Trigonometric relation

from 1 and 2

Therefore bird is from point C

true

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)
