Answer:
4860 ft^2
Step-by-step explanation:
9 feet is represented by 1 inch.
● 9 => 1
Square both sides
● 81 => 1
So a 81 ft^2 square is represented by a 1 in^2 square (picture below)

The gym's area in the blueprint is 60 in^2
That 60 1in^2 squares.
● 1 => 81
● 1×60 => 81×60
We have multiplied both sides by 60
● 60 => 4860
So the original are is 4860 ft^2

If a jacket is on sale for 35% off, that means that the price of the jacket is % of its original price.
We can find 65% of 140 by making 65% into a decimal - 0.65, then multiply it by 140.
Hope this helped!
Answer:
2tanθ = 2cotθ
tanθ = cotθ
tanθ = 1 /tanθ
tan²θ = 1
tanθ = ±1
if tanθ = 1
θ = 45° + nπ (π = 180° , n is a natural number)
if tanθ = -1
θ = 135° + nπ
I feel like it is B hope this helps
