Step-by-step explanation:
It's been a while since I used trigonometry, but here is what I got.
We know that 44 degrees in the angle from the string to the base of the ground.
We also know that the length from that angle to the base of the tree is 90 feet.
So using the SOH, CAH, TOA rule we know that to figure out the opposite side (x) length using the adjacent side (90) length we need to use tangent of 44 degrees.
The equation should be tan(44°) = x/90
Tan(44°)=0.96589
Now you multiply that number by 90 to find x.
Hope that helped, let me know if it did or not.
