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.
Step-by-step explanation:
So the box is rectangular prism of 8x8x8, namely a cube with all sides of 8 units long.
check the picture below, the cube is just 6 squares stacked up to each other at the edges, and each square is a 8x8.
so, just get the area of all 6 squares, sum them up and that's the surface area of the box, 6(8*8).
The transformation(s) that can be used to map one triangle onto the other is : (C). dilation, then translation
<h3>Meaning of dilation and translation</h3>
Dilation can be defined as the process of compressing and reducing a shape to a particular scale
Translation can be defined as a process of transferring a shape from one point to another.
In conclusion, The transformation(s) that can be used to map one triangle onto the other is : (C). dilation, then translation

Step-by-step explanation:
delta math
The computation shows that the total cost will be $66.
<h3>How to calculate the value?</h3>
From the information, Ari rents the bike for 4 hours, and meg rents the scooter for 3 hours.
The total cost will be:
= (4 × $9) + (3 × $10)
= $36 + $30
= $66
.
Therefore, the computation shows that the total cost will be $66.
