7.5 - 3.2 = 4.3 + 4 = 8.3^3 = 571.787 ÷ 2 = 285.8935 rounded to 285.9
Answer:
![\theta=41.18^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D41.18%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given that,
The height of the tree, h = 14 ft
The height of the shadow, b = 16 ft
We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
![\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{14}{16}\\\\\theta=41.18^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7BP%7D%7BB%7D%5C%5C%5C%5C%5Ctan%5Ctheta%3D%5Cdfrac%7B14%7D%7B16%7D%5C%5C%5C%5C%5Ctheta%3D41.18%5E%7B%5Ccirc%7D)
So, the required angle of elevation of the sun is equal to
.
