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)
The answer is B (-3).

Answer:
11/4 = 5/4
If you need 5/4 cups of sugar to make 20 cookies or in other words,
For 20 cookies you need 5/4 cups of sugar then
for 14 cookies you will need: 14 * (5/4)/20 = 7/8 cups of cookies
if you like a very sweet cookies then you can add a bit more sugar to make it 1 full cup of suger
