A painter can paint 350 square feet in 1.25 hours. What is the painting rate in square feet per hour?

blsea [12.9K]

Well we know that he can paint 350 square feet in 1.25 hours. To find how much he can paint in 1 hour, we would divide 350 by 1.25. 350 divided by 1.25 = 280, therefore his painting rate is 280 square feet per hour.

2tan(45-A)/1+tan^2(45-A)=cos2a

AVprozaik [17]

Answer:

Let θ = (45 - A)°.

=> 2Tanθ/ 1 + Tan²θ

=> 2Sinθ/Cosθ / 1 + Sin²θ / Cos²θ

=> 2Sinθ/Cosθ/ Cos²θ + Cos²θ / Cos²θ

=> 2Sinθ/Cosθ/ 1 / Cos²θ

=> 2SinθCos²θ/Cosθ

=> 2SinθCosθ

=> Sin2θ

But we assumed θ = (45 - A)°,

=> Sin2(45 - A)

=> Sin(90 - 2A) (∵ Sin(90 - θ) = Cosθ)

=> Cos2A

= R.H.S

Hence proved.
