Answer:
8
Step-by-step explanation:
6*(n + 15) = -42
Divide both sides by 6
6*(n - 15)/6 = -42/6
n - 15 = -7
n = -7 + 15
n = 8
n-4=385. The answer is 389
17x15=255ft
255ft
Hope this helps
use SOHCAHTOA
S = sine
O = opposite edge
H = hypotenuse
T = Tangent
A = adjacent edge
C = cosine.
The extreme is where the runaway is indicated by the hypotenuse is the required distance. Therefore,
sine 7= 3/H
H = 3/sine 7= 24mi
