F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
Answer:
23°
Step-by-step explanation:
We apply Pythagorean theorem to determine the missing length, Hypotenuse:

This hypotenuse corresponds to the right triangle and the tree's height, corresponds to the angle of elevation:
-We apply the law of Sines;

Hence, the angle of elevation is 23°
