An office building is 52 feet away from where Ian is standing. A sign is placed on top of the office building. From the point on the ground where Ian is standing, the angle of elevation to the top of the sign and the angle of elevation to the bottom of the sign are 40∘(degrees) and 32∘(degrees), respectively as shown in the diagram below.

the answer is 13 cm

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
