Using the Law of Sines, sina/A=sinb/B=sinc/C (although there are other ways considering that this is a 30, 60, 90 degree triangle with a basic identity) we can say:
97/sin60=x/sin30=y/sin90
x=97sin30/sin60 and y=97sin90/sin60
The total height of the tree is h=x+y so
h=97sin30/sin60 + 97sin90/sin60
h≈168.01 ft (to the nearest hundredth of a foot)
h≈168 ft (to nearest foot)
U multiply it as u would multiply a two digit and a one digit number step by step only then u have to multiply the second number like u did to the other number and u add a zero then add them and u get ur answer

EASY IVE DONE IT
Draw it. It's a right triangle, with a base of 6 feet and a height of 4 feet. Now all you need is Pythagoras' theorem, a^2 + b^2 = c^2.
The height can be a, the base can be b, so all you need is to solve for c, which is the rope.
The rest is left as an exercise to the reader
