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

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
