Step-by-step explanation:
To understand the problem clearly, you have to illustrate it. Based on my understanding, the problem goes like this. Please refer to the picture. When the sun is high up in the sky, it causes a shadow to form. In the picture, this is represented by the bold horizontal line to the ground that measures 27.6 m. You want to find the angle of elevation of the sun, denoted as x°. With the height of the tree being 18 m, you create a right triangle. Therefore, we can apply the pythagorean theorems.
With respect to the unknown angle, you know the opposite side (18 m) and the adjacent side (27.6 m). So, it would be easier to use the tangent function.
tan x° = opposite/adjacent = 18/27.6
x = tan^-1 (18/27.6)
x = 33.11°
Answer:
All you need to do is move all terms to the left side and set equal to zero
The Answer is x = 16 Hope this helps :)

Answer:
1/64
Step-by-step explanation:
Rewrite the expression using the negative exponent rule b⁻n = 1/bⁿ.
1/16³/²
simplify the denominator
rewrite 16 as 4²
1/(4²)³/²
Apply the power rule and multiply exponents, (aⁿ)ᵃ=aⁿᵃ
1/4²(³/²)
Cancel the common factor of 2
Cancel the common factor
then rewrite the expression
1/4³
Raise 4 to the power of 3
1/64
