Answer: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
The answer is choice A
The line is RS because R and S are on the line.
The plane is RSU because we need at least 3 non-collinear points to form a plane. In this case, point U is not on line RS.
Answer: 2.26 * 10^4
Step-by-step explanation:
Answer:
First pilot will gain altitude faster by 7.16 mph than second pilot.
Step-by-step explanation:
In this question we will calculate the y component of the velocity by which the pilots are gaining height. Means we will analyze which pilot will gain the altitude early.
For the first pilot vertical component of the velocity will be
v = 400 × sin30° = 400 × (1/2) = 200 mph
For second pilot vertical component of the speed is
v' = 300 × sin40° = 300 × (0.642) = 192.84 mph
Therefore pilot 1 will gain altitude faster then pilot 2 by
200 - 192.84 = 7.16 mph.
