From a window 40 feet above the ground in a certain building, the angle of elevation to a window in a second building is 43 degrees. If the distance between the buildings is 110 feet how far above ground level is the second window.
If x+40 is the height of the second window what is the first step;
a)tan43 degrees= x/110
b)sin43 degrees =x/110
c)sin43 degrees =110/x
d)tan43 degrees =110/x
Thank you in advance for your help.
