Answer
given,
height of the light house = 292 foot
angle of depression of ship = 36°
angle of elevation of plane = 20°
Assuming the height of the plane above tower be 'h'
now
for distance of ship
![tan \theta = \dfrac{P}{B}](https://tex.z-dn.net/?f=tan%20%5Ctheta%20%3D%20%5Cdfrac%7BP%7D%7BB%7D)
![tan 36^0 = \dfrac{292}{B}](https://tex.z-dn.net/?f=tan%2036%5E0%20%3D%20%5Cdfrac%7B292%7D%7BB%7D)
![B = \dfrac{292}{0.727}](https://tex.z-dn.net/?f=B%20%3D%20%5Cdfrac%7B292%7D%7B0.727%7D)
B= 401. 9 ft
height of the plane
![tan \theta = \dfrac{P}{B}](https://tex.z-dn.net/?f=tan%20%5Ctheta%20%3D%20%5Cdfrac%7BP%7D%7BB%7D)
![tan 20^0 = \dfrac{h}{401.9}](https://tex.z-dn.net/?f=tan%2020%5E0%20%3D%20%5Cdfrac%7Bh%7D%7B401.9%7D)
![h = 401.9 \times 0.364](https://tex.z-dn.net/?f=h%20%3D%20401.9%20%5Ctimes%200.364)
h= 146.28 ft
height of plane from ground = 292 + 146.28
= 438.28 ft
Answer:
Because he expects students to do good research and present their findings with consistent data and arguments. In other words, he has a lot of expectations for the class and believes in the students' potential, so he wants to stimulate them.
Explanation:
