A ball is thrown upward from the top of a building that is 160 feet tall. The height, h, of the ballt seconds after being thrown is given by the equation h = -16t2 + 48t + 160. After how many seconds will the ball hit the ground?
A) 2
B) 3
C) 5
D) 10

answer: okw

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.
