For this case we have an exponential equation of the form:

Where,
- <em>A: initial value
</em>
- <em>b: decrease rate
</em>
- <em>x: number of years
</em>
Substituting values in the given equation we have:

Answer:
Explanation:
<u>1) Data:</u>
a) height of the person = opposite-leg to the angle the sun makes with the ground = 5 ft
b) length of the shadow = adjacent-leg to the angle the sun makes with the ground = 12 ft
c) angle, α = ?
<u>2) Solution</u>
- tanα = opposite-leg / adjacent-leg
- tanα = 5 ft / 12 5t = 5/12
- 22.6° rounded to the nearest degree is 23° ← answer
