Answer:
The total change in his account is of -$85, that is, a loss of $85
Step-by-step explanation:
We combine these changes. So
On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.
On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70
On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85

Answer:
![WY=42.8\ units](https://tex.z-dn.net/?f=WY%3D42.8%5C%20units)
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle WYS
Applying the Pythagoras Theorem
![WY^{2}=WS^{2}+YS^{2}](https://tex.z-dn.net/?f=WY%5E%7B2%7D%3DWS%5E%7B2%7D%2BYS%5E%7B2%7D)
we have that
![WS=XZ=42\ units](https://tex.z-dn.net/?f=WS%3DXZ%3D42%5C%20units)
![YS=YZ-WX=19-11=8\ units](https://tex.z-dn.net/?f=YS%3DYZ-WX%3D19-11%3D8%5C%20units)
substitute
![WY^{2}=42^{2}+8^{2}](https://tex.z-dn.net/?f=WY%5E%7B2%7D%3D42%5E%7B2%7D%2B8%5E%7B2%7D)
![WY^{2}=1,828](https://tex.z-dn.net/?f=WY%5E%7B2%7D%3D1%2C828)
![WY=42.8\ units](https://tex.z-dn.net/?f=WY%3D42.8%5C%20units)
