Answer:
About 30.98386677 ft above the water.
Step-by-step explanation:
Use pythagorean theorem, a^2+b^2=c^2.
So when you plug in the numbers it would be x^2+22^2=38^2. Move 22^2 to the right side giving you x^2=38^2-22^2. Then subtract and take the square root of x^2.
Answer:
Step-by-step explanation:

3x + 3 = 39
3x = 36
x = 12 years
