Answer:
The surfacearea of the box would 140 length (14 times 10), 125 width (12.5 times 10), and 10 height(1 times 10). Therefore2ラ(140ラ125 + 140ラ10 + 125ラ10) = 40,300 centimeters^2
Answer:
2/7
Step-by-step explanation:
Let the angle = x
Using the figure below, to find x, setup the equation:
x+70+x=180
2x+70=180
2x=110
x=55°
So the ball hits the surface at 55° and bounces back at 55°.
Answer: 55°
Answer:
(x - 6)^2 + (y + 2)^2 = (x - 2)^2 or -8 x + y^2 + 4 y + 36 = 0
