Susan needs to know the elevation gain from the floor of yosemite valley to the top of el capitan, a cliff on one side of the valley. she measures 3300 feet between two boulders on the valley floor next to the cliff and sights the top of el capitan at angles of 17 degrees and 23 degrees. find distance between each of the boulders and the top of el capitan.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

answer: 7. if the functions had a negative leading coefficient and is of even degree, which statement about the graph is true?

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
