Answer:
Step-by-step explanation:
The manager visits a park and interviews people who are waiting to use the tennis courts.
<span>Consider a angle â BAC and the point D on its defector
Assume that DB is perpendicular to AB and DC is perpendicular to AC.
Lets prove DB and DC are congruent (that is point D is equidistant from sides of an angle â BAC
Proof
Consider triangles ΔADB and ΔADC
Both are right angle, â ABD= â ACD=90 degree
They have congruent acute angle â BAD and â CAD( since AD is angle bisector)
They share hypotenuse AD
therefore these right angle are congruent by two angle and sides and, therefore, their sides DB and DC are congruent too, as luing across congruent angles</span>
Step 
In the right triangle ADB
<u>Find the length of the segment AB</u>
Applying the Pythagorean Theorem
we have
substitute the values
Step 
In the right triangle ADB
<u>Find the cosine of the angle BAD</u>
we know that
Step 
In the right triangle ABC
<u>Find the length of the segment AC</u>
we know that
solve for AC
Step 
<u>Find the length of the segment DC</u>
we know that
we have
substitute the values
Step 
<u>Find the length of the segment BC</u>
In the right triangle BDC
Applying the Pythagorean Theorem
we have
substitute the values
therefore
<u>the answer is</u>

Hey
Definition:-
A square root is a number which produces a specific quantity when multiplied by itself.
Example:-
Suppose the area of a square of side 6 cm is given by 6 × 6 = 36 cm².
Therefore 36 is said to be the square of 6. We write 6² = 36 and we read the ‘the square root of 6 is 36' or simply ‘6 squared is 36.'
hope this helps
