C) 100
D) 64

x = 64

Step-by-step explanation:

Using the Altitude - on - Hypotenuse theorem.

The altitude is drawn to the hypotenuse of a right triangle, then

36x = 48² = 2304 ( divide both sides by 36 )

x = 64

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
