Perctange is based on the total number. in this case you don't know it so you cant make such a guess.
The answer would be (8h+24).
Answer:
![y=2^{x}\ -3](https://tex.z-dn.net/?f=y%3D2%5E%7Bx%7D%5C%20-3)
Step-by-step explanation:
Answer:
<u>The correct answer is the letter C. </u>
Step-by-step explanation:
We can use the following trigonometric identity:
(1)
(2)
Solving each equation by b and equaling we have:
![\frac{6}{cos(60)}=\frac{c}{cos(45)}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7Bcos%2860%29%7D%3D%5Cfrac%7Bc%7D%7Bcos%2845%29%7D)
![\frac{6}{cos(60)}=\frac{c}{cos(45)}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7Bcos%2860%29%7D%3D%5Cfrac%7Bc%7D%7Bcos%2845%29%7D)
Let's recall that:
Then we have:
![c=\frac{cos(45)*6}{cos(60)}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7Bcos%2845%29%2A6%7D%7Bcos%2860%29%7D)
Using equation (1) we can find b.
Finally, we can find a using the next equation:
![tan(60)=\frac{a}{6}](https://tex.z-dn.net/?f=tan%2860%29%3D%5Cfrac%7Ba%7D%7B6%7D)
<u>Therefore, the correct answer is the letter C. </u>
I hope it helps you!
Answer:
tanA = sinA / cosA = 3/5 / 4/5 = 3/4.
