The bottom floor of a parking garage is an elevation of -36 feet. The top floor is 124 feet higher. What is the elevation of the top floor?

88 feet.

Step-by-step explanation: For this problem, to find the elevation of the top floor we will simply subtract 36 feet from 124 feet, or we could add -36 feet to 124 feet.

124 + (-36) Is like subtracting 124 - 36.

So, 124 + (-36) = 88

This means that the elevation of the top floor is 88 feet.

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.
