Question

A ramp descends 2m from a point 10m long. What is the angle of inclination of the ramp?

a) 10 degrees
b) 20 degrees
c) 30 degrees
d) 45 degrees

Answer 1

To find the angle of inclination of the ramp, we can use trigonometry. The ramp descends 2m over a distance of 10m.

Step-by-step explanation:

To find the angle of inclination of the ramp, we can use trigonometry. The ramp descends 2m over a distance of 10m. The angle of inclination can be found using the formula:

Angle of inclination = arc tan (height/length)

Substituting the values, we get:
Angle of inclination = arc tan (2/10)

Using a calculator, the angle of inclination is approximately 11.3 degrees. Therefore, the correct answer is a) 10 degrees.
