Starting at point 0, you travel 500 m on a straight road that slopes upward at a constant angle of 5 degrees. What is your height above the starting point? Answer in meters to the nearest centimeter

43.58 m

Explanation:

If you travel 500 m on a straight road that slopes upward at a constant angle of 5 degrees

Using trigonometry ratio

Sin 5 = opposite/hypothenus

Where the hypothenus = 500m

Opposite = height h

Sin 5 = h/500

Cross multiply

500 × sin 5 = h

h = 500 × 0.08715

h = 43.58m

Therefore, the height above the starting point is equal to 43.58m

increased life expectancy and

migration.
