Aroad is inclined at an angle of 5. after driving 5,231 feet along this road, find the driver's increase in altitude.

456 ft

Step-by-step explanation:

In the diagram below, a represents the driver’s increase in altitude.

            sin(5°) = a/5231   Multiply each side by 5231

    5231sin(5°) = a

5231 × 0.0872 = a

                     a = 456 ft

The driver’s increase in altitude is 456 ft.
