Answer:
10.99
Step-by-step explanation:
![tan20 = \frac{ac}{bc} \\ bc = \frac{ac}{tan20} \\ = \frac{4}{tan20} \\ = 10.99](https://tex.z-dn.net/?f=tan20%20%3D%20%20%5Cfrac%7Bac%7D%7Bbc%7D%20%20%5C%5C%20bc%20%3D%20%20%5Cfrac%7Bac%7D%7Btan20%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B4%7D%7Btan20%7D%20%20%5C%5C%20%20%3D%2010.99)
where you see tan20 the 20 has a degree sign on top
Answer:
(1,0)
I hope this is good enough:
<em>10 meters.</em>
Step-by-step explanation:
To find the missing side of a right triangle, we can use the <u>Pythagorean theorem</u>.
The Pythagorean theorem is...
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Please be sure to note that a and b will <em>always </em>be the length of the sides and c will <em>always </em>be the hypotenuse, or in this case the ramp.
Since we know the values of both of the sides we can plug this into the theorem.
![6^2+8^2=c^2](https://tex.z-dn.net/?f=6%5E2%2B8%5E2%3Dc%5E2)
Now we can solve.
![36+64+c^2](https://tex.z-dn.net/?f=36%2B64%2Bc%5E2)
Add.
![100=c^2](https://tex.z-dn.net/?f=100%3Dc%5E2)
Many people will make the mistake of thinking 100 is the final answer, but since c is squared we need to find the square root of 100.
![\sqrt{100} =10](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D%20%3D10)
c = 10
<em><u>The ramp is 10 meters.</u></em>
