The the geometrics decide to play a concert in the gym. the gym measures 100 feet long by 60 feet wide by 30 feet tall. the band asks the stage crew how loud they can play in the gym. after some experimenting, the stage crew calculates that the band can turn up the amplifier volume one notch for every 18,000 ft.³. so how loud can the geometrics have their amplifiers in this room?

no idea

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
