The equation that must be true about the rotation is that m∠EAE ' = m∠FAF.
<h3>How to explain the rotation?</h3>
Rotation is a type of transformation in which the shape of the original object is preserved and the angle of rotation is constant for all the parts of the body.
In this case, ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F, m∠EAE ' = m∠FAF.

Answer:
6/1 x 2/3
Step-by-step explanation:
You would have to divide 100,000 by 467 which is 214.1327623 then round up so no one is left behind so you would have to make 215 trips
Answer:
First, you have to find out the surface area of the box
=> Sbox = 10 x 5 x 2 + 10 x 8 x 2 + 5 x 8 x 2 = 340
Denote Surface area of the ball as Sball, we have:
Sball + Sbox = 352.56
=> Sball = 352.56 - Sbox = 352.56 - 340 = 12.56
From the formula to calculate Sball, we have:
4 x pi x radius^2 = 12.56
=> radius^2 = 12.56/(4 x pi) = 1 (here, pi = 3.14)
=> radius = 1 in
Hope this helps!
