Answer:
![\theta=0.99^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D0.99%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given that,
The height of a cell tower, P = 70 m
The tower casts a shadow of 45 meters on the ground.
We need to find the angle of elevation of the shadow to the top of the cell tower. We can use trigonometry to find it.
![\tan\theta=\dfrac{P}{B}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7BP%7D%7BB%7D)
Put all the values,
![\tan\theta=\dfrac{70}{45}\\\\\theta=\tan^{-1}\left(\frac{70}{45}\right)\\\\\theta=0.99^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B70%7D%7B45%7D%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%5Cleft%28%5Cfrac%7B70%7D%7B45%7D%5Cright%29%5C%5C%5C%5C%5Ctheta%3D0.99%5E%7B%5Ccirc%7D)
Hence, the angle of elevation is equal to
.
Answer:
2. 135
3. 8
4. 9/49 or 0.18367346…
5. b2/125
Step-by-step explanation:
( I couldn't see what b was equal to if you showed it. And the b2 is b squared)
The answer in the green box should be 9.
