Answer:
<h2>
Length x width x height</h2>
Step-by-step explanation:
This is how you get the area of a shape.
For this case we can model the problem as a rectangle triangle.
We know:
Length of the hypotenuse
Angle between the base of the triangle and the hypotenuse.
We want to know:
Length of the base.
For this we use the following trigonometric relationship:
![cos (15) = \frac{x}{500} ](https://tex.z-dn.net/?f=cos%20%2815%29%20%3D%20%5Cfrac%7Bx%7D%7B500%7D%20%0A)
Clearing x we have:
![x = 500 * cos (15) x = 482.96](https://tex.z-dn.net/?f=x%20%3D%20500%20%2A%20cos%20%2815%29%0A%0Ax%20%3D%20482.96)

Answer:
The horizontal distance she has covered is:
Answer:
4. dy/dx = -2
8. dy/dx = 1/2 x^(-3/2)
10/ dy/dr = 4 pi r^2
Step-by-step explanation:
4. y = -2x+7
dy/dx = -2(1)
dy/dx = -2
8. y = 4 - x^-1/2
dy/dx = - (-1/2x^ (-1/2-1)
dy/dx = 1/2 x^(-3/2)
10. y = 4/3 pi r^3
dy/dr = 4/3 pi (3r^2)
dy/dr = 4 pi r^2
Do the Pythagorean theory to find the unknown side by doing:
c^2 = a^2 - b^2
Then you’ll have two sides and two angles.
Do sine law.
Sin(angle) / side (opposite to it) = Sin(angle) / side (opposite to it)
