1. Mr. Morrison has decided that an angle of 15° is
about the right measurement for the ramp. He
measures the height of the front doorstep. It is 12
cm high.
12cm
How long will the sloping piece of wood for the ramp need to be?
3.21
O 46.36
12.42
44.78

answer4 to the second power is 16

and 4 to the third power is 64,

add 8+12 to get a simplified answer of 12r-20

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
