The answer is C because if any of those are not parallel will not make the angle similarity true.
Using the cosine function:
![\begin{gathered} \cos (\theta)=\frac{_{\text{ }}adjacent}{_{\text{ }}hypotenuse} \\ so\colon \\ \cos (45)=\frac{b}{16} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ccos%20%28%5Ctheta%29%3D%5Cfrac%7B_%7B%5Ctext%7B%20%7D%7Dadjacent%7D%7B_%7B%5Ctext%7B%20%7D%7Dhypotenuse%7D%20%5C%5C%20so%5Ccolon%20%5C%5C%20%5Ccos%20%2845%29%3D%5Cfrac%7Bb%7D%7B16%7D%20%5Cend%7Bgathered%7D)
Solve for b:
Answer:
area = 12 m²
Step-by-step explanation:
area = L x W
area = 4 x 3 = 12 m²
Answer:
.5236
Step-by-step explanation:
Formula for sphere volume:
V = ![\frac{4}{3} \pi r^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E%7B3%7D)
substiture 0.5 for r:
= .5236
The student would earn %86. To calculate percentage you take the amount of questions correct, divide that by the amount of questions given, multiply by 100 and round to the nearest percent.
