Answer:

Step-by-step explanation:
1) Add 8 to both sides.
<em />
2) Divide both sides by 2.

3) Simplify
to 4.

4) Take the cube root of both sides.
![x=\sqrt[3]{4}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B4%7D)
5) Rewrite 4 as 2².
![x=\sqrt[3]{2^2}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B2%5E2%7D)
6) Use this rule:
.

Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC

Hypotenuse ^2 = 8^2 + 21^2
hypotenuse = 
= 
= 
= 22.47
So the length of the hypotenuse is 22.47 m
So what we know from that is that angle is 30 degrees south of west. so you go 30 degrees down from west. How can we do this? well <span>basically what you have to do is to break down the force into x and y component. The y component of large force and the y component of small force should cancel so that the boat doesn't go north and south and the x components of both the forces should add up so that it goes west only.</span>
