Most fool-proof way to do this in my opinion is to simply expand everything and write it out, i.e.
Throwing this into a calculator, we get
23.032To the nearest cent, this gives us
$23.03
Answer: 4 hours
Step-by-step explanation: you have to divide 240 by 60 which is 4
If this is too hard for you remember you can divide 24 by 6 and get the same answer hope this helps mark me brainliest if it helped
From the figure, we immediately have
cos(θ) = 8/17
sin(θ) = 15/17
By definition of tangent,
tan(2θ) = sin(2θ)/cos(2θ)
Recall the double angle identities:
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1
Then
tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)
tan(2θ) = (2 × 15/17 × 8/17) / (2 × (8/17)² - 1)
tan(2θ) = -240/161
