The design plans for a new concert hall show elevations relative to ground level at 0 feet. The elevation of the balcony floor is 37 feet, and the elevation of the basement floor is -17 feet. How many feet above ground level is the balcony floor?

The bacony floor is 37 feet above the ground floor.

Step-by-step explanation:

Here, the ground level is marked as 0 feet.

The elevation of the balcony floor is 37 feet.

The elevation of the basement floor is -17 feet.

Since elevations relative to ground level at 0 feet.

i.e. elevation of balcony floor is same as the distance of balcony floor from ground.

That means the bacony floor is 37 feet above the ground floor.

Hence, the bacony floor is 37 feet above the ground floor.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
