Question

Jake plans to use a ramp to make it easier to move a piano out of the back of his truck. The back of the truck is 838383 centimeters tall and the ramp is 158158158 centimeters long.

Answer 1

To determine if a ramp will make it easier to move a piano, you can calculate the angle of the ramp using trigonometry.

Step-by-step explanation:

When using a ramp to move a piano, you need to consider the height of the truck and the length of the ramp. In this case, the truck is 838383 centimeters tall and the ramp is 158158158 centimeters long. To determine if the ramp will make it easier to move the piano, you can calculate the angle of the ramp using trigonometry. The angle can be found by taking the inverse tangent of the height of the truck divided by the length of the ramp. Once you have the angle, you can determine if it is steep enough to make it easier to move the piano.

Answer 2

134.44 cm

Step-by-step explanation:

Given that:

Length of ramp, = 158 cm

Height of truck, = 83 cm

The distance from end of ramp to base of truck ;

Using Pythagoras rule :

The diagram is in the picture attached ;

Opposite = sqrt(hypotenus² - adjacent²)

d = sqrt(158² - 83²)

d = sqrt(24964 - 6889)

d = sqrt(18075)

d = 134.44 cm
