Answer:
192
Step-by-step explanation:
x is the altitude of the right triangle. Thus, we would apply the geometric mean theorem to find the value of x. Thus, the formula is given as:
h = √(ab)
Where,
h = altitude = x
a = 144
b = 400 - 144 = 256
Plug in the given values into the formula
x = √(144*256)
x = √(36,864)
x = 192
