3. Maple bought a new car, and wants to ride it to the top of a mountain and visit a lookout point. If they drive

4000 meters along a road that rises 1480 meters up as

she drives. What is the angle of inclination that Maple

drove their car?

Answer :

The angle of inclination that Maple drove their car is approximately 21.67⁰.

- The rise (vertical distance) is 1480 meters.

- The road (hypotenuse) is 4000 meters.

The sine of the angle of inclination \(\theta\) is given by:

[tex]\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} = \frac{1480}{4000}[/tex]

Compute the ratio:

[tex]\sin(\theta) = \frac{1480}{4000} = 0.37[/tex]

Take the inverse sine (arcsine) of 0.37 to find [tex]\theta[/tex]

[tex]\theta = \arcsin(0.37)[/tex]

[tex]\theta = \arcsin(0.37) \approx 21.67^\circ[/tex]

So, the angle of inclination that Maple drove their car is approximately 21.67⁰.
