Answer:
BC = 10 m ; CA = 5√3 m
Step-by-step explanation:
A right triangle with an angle of 60 degrees is half of a equalteral one
BC (the hypotnuese) is double the minor length (BA)
BC = 10 m
CA (the height) can be expressed as the minor leg multiply by √3
CA = 5√3 m
Answer:
11.25 minutes
Step-by-step explanation:
The capacity of the swimming pool is 105 gallons of water.
There are currently 15 gallons of water
∴I need to fill (105-15) = 90 gallons of water
Now,
8 gallons of water are filled within 1 minute
∴1 gallon of water will be filled within = 1/8 minute
∴90 gallons of water will be filled within = 90/8 minutes
=11.25 minutes
