<h3>Answer:  9.4 feet</h3>

Work Shown:

sin(angle) = opposite/hypotenuse

sin(22) = x/25

x = 25*sin(22)

x = 9.3651648353978

x = 9.4

Your calculator needs to be in degree mode. One way to check is to compute sin(30) and you should get 0.5 or 1/2.

If f(a) = K, then which of the following must be true? f(K) = a f -1(K) = a f -1(a) = K
Inessa05 [86]

Answer:


Step-by-step explanation:

given that f(a) = K

we have the options of

f(K) = a

f ⁻¹ (K) = a

f ⁻¹ (a) = K

Where f ⁻¹ denotes an inverse function.

If f(a) = K, then its reciprocate, f ⁻¹ (K) = a

because it is essentially undoing the original equation
