Answer:

Step-by-step explanation:

you need the arc length formula .. do you have it?

s = r ∅

s is the arc length in radians but you can make it in degrees just by

using s = 2πr (θ/360)

the angle is 180 for the picture.

so the arc length is just $\pi$ r

r= 4

$\pi$ *4 = 12.56637.... approx

Anyone wanna help me out??

Burka [1]

Answer:

6955 ft

Step-by-step explanation:

Refer to attached. Point J, segment BJ and angle measures added.

Step 1, find BJ

BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ft

Step 2, find BP

BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ft

Step 3, find PQ

PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ft

Step 4, find the elevation of peak P

Height above sea level = 6500 + 454.7 ≈ 6955 ft (rounded)
