Given: ΔABC, AC = BC, AB = 3 CD ⊥ AB, CD = √3 Find: AC

Step-by-step explanation:

AD = BD  (CD bisects AB means that it divides the line into two equal parts)

So,

AD = BD = AB/2

So,

AD = 3/2

AD = 1.5

Now, Finding AC using Pythagorean Theorem:

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)

Taking sqrt on both sides

Step-by-step explanation:

The length of AB is 3 units.

The length of CD is units.

D is the mid-point of points A and B.

AD is half of AB.

Apply Pythagorean theorem to solve for length of AC.

The hypotenuse is length AC.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
