First thing plot a right angle with angle of elevation of 35degrees as shown in figure then use SOHCAHTOA.
Ay/Helicopter = sin 35
Ay = 86 sin 35 = 36.8237
Ax/Helicopter = cos 35
Ax = 86 cos 35 = 77.7175
Note: I ignore the negative signs coz they signify direction
Answer:
length of a quarter wavelength antenna for transmitter elf waves are zero
Explanation:
Find the length of a quarter wavelength antenna for transmitter elf waves
Given information
frequency (ELF waves) → 77Hz
Speed of light → 3
m/s
where
→ wavelength of the antenna
f → frequency of the ELF waves
→ speed of light
so rewrite the equation in 
from
Substitute 
=
Substitute 75Hz = f
m
since we get this value,but this size of antenna mount on submarine is not possible.
so is zero
361 cubic meters of habitable space was available in the skylab. None of the given options are correct.
<h3>Who launched skylab?</h3>
NASA launched the first American space station, called Skylab.
The fuel tank of the Saturn SIV-B rocket stage served as the Skylab's residential quarters.
Skylab's livable capacity was large in comparison to the spacecraft that American astronauts had previously used 361 cubic meters.
Skylab offered 361 cubic meters of livable area.
Hence, none of the given options is correct.
