Answer:
Step-by-step explanation:
let the number be x %
according to the question the equation is
x% of 15=45
x/100*15=45
15x=45*100
x=4500/15
x=300
therefore x=300%
Answer: 16.91°
Step-by-step explanation:
1. You can draw a right triangle as you can see in the figure attached.
2. Then you can calculate the angle of elevation (α) as following:
![\alpha=arcsin(\frac{opposite}{hypotenuse})](https://tex.z-dn.net/?f=%5Calpha%3Darcsin%28%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%29)
Where:
![opposite=32\\hypotenuse=110](https://tex.z-dn.net/?f=opposite%3D32%5C%5Chypotenuse%3D110)
3. Now you must substitute these values. Then, the angle of elevation is:
![\alpha=arcsin(\frac{32}{110})](https://tex.z-dn.net/?f=%5Calpha%3Darcsin%28%5Cfrac%7B32%7D%7B110%7D%29)
![\alpha=16.91\°](https://tex.z-dn.net/?f=%5Calpha%3D16.91%5C%C2%B0)
Use the distributive property to get 8x+28+6x+21 then combine 8x and 6x and also combine 28 and 21 to get 14x+49, do u need to go further or?
