True
Step-by-step explanation:
Some of our energy comes from electrical power plants
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)
Answer:
r =9.5
Step-by-step explanation:
The radius is 1/2 of the diameter
r = d/2
r = 19/2
r =9.5
