Answer:
![\frac{x}{\sqrt{x^2+9}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B%5Csqrt%7Bx%5E2%2B9%7D%7D)
Step-by-step explanation:
Let
.
Then
.
Construct a right triangle.
Make one of the non-right angles
.
Recall
is equal to the ratio of the side that is opposite to
to the side that is adjacent to
.
This means opposite side
while adjacent side
since
.
We can find the hypotenuse by using the Pythagorean Theorem.
![(x)^2+(3)^2=(\text{hyp})^2](https://tex.z-dn.net/?f=%28x%29%5E2%2B%283%29%5E2%3D%28%5Ctext%7Bhyp%7D%29%5E2)
![x^2+9=(\text{hyp})^2](https://tex.z-dn.net/?f=x%5E2%2B9%3D%28%5Ctext%7Bhyp%7D%29%5E2)
Take the square root of both sides:
.
Recall
is equal to the ratio of the side that is opposite to
to the hypotenuse.
![\sin(\arctan(\frac{x}{3}))](https://tex.z-dn.net/?f=%5Csin%28%5Carctan%28%5Cfrac%7Bx%7D%7B3%7D%29%29)
-->Because we let the inside equal
.
-->Because ![\sin(u)=\frac{\text{opp}}{\text{hyp}}](https://tex.z-dn.net/?f=%5Csin%28u%29%3D%5Cfrac%7B%5Ctext%7Bopp%7D%7D%7B%5Ctext%7Bhyp%7D%7D)
Answer:
140.8 cm2
Step-by-step explanation:
a spare has 4 sides so you need to times 35.2 by 4 which is 140.8
