Answer:
40.3 feet
Step-by-step explanation:
Use trigonometry.
First, set your calculator to Degrees instead of Radians. Next, draw a model like the attached image to help you better understand the question.
Now, figure out which trigonometric ratio to use. In this case, it is easiest to use sine (or cosine).
sin(38°) = x / 125
125(sin(38°)) = x
x ≈ 37.046
Finally, to find the height, simply add how high the hand is from the ground:
h = 37.046 + 3.25 = 40.296
So,
h ≈ 40.3 ft
First you would need to apply the distributive property on the left side to get rid of the parenthesis. Then, you would need to apply the square root on both sides of the equation. Once this is done you would just need to solve for x.
