Answer:
≈ ![21.21\ ft](https://tex.z-dn.net/?f=21.21%5C%20ft)
Step-by-step explanation:
Observe the figure attached.
You need to use the following Trigonometric function in order to find the length of the diagonal "d":
![cos\alpha=\frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cos%5Calpha%3D%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
For this case:
![\alpha=45\°\\adjacent=15\\ hypotenuse=d](https://tex.z-dn.net/?f=%5Calpha%3D45%5C%C2%B0%5C%5Cadjacent%3D15%5C%5C%20hypotenuse%3Dd)
Therefore, you need to substitute these values into the Trigonometric function and solve for "d":
![cos(45\°)=\frac{15}{d}\\\\d*cos(45\°)=15\\\\d=\frac{15}{cos(45\°)}](https://tex.z-dn.net/?f=cos%2845%5C%C2%B0%29%3D%5Cfrac%7B15%7D%7Bd%7D%5C%5C%5C%5Cd%2Acos%2845%5C%C2%B0%29%3D15%5C%5C%5C%5Cd%3D%5Cfrac%7B15%7D%7Bcos%2845%5C%C2%B0%29%7D)
≈ ![21.21\ ft](https://tex.z-dn.net/?f=21.21%5C%20ft)
Monday: 9 times 4= 36 dollars
36 times 5 equals 180. So the team earned 180 dollars altogether on Monday and Tuesday
I think the answer is 5 not sure tho
I believe the height is 9
