Answer:

Step-by-step explanation:

DE² = 29² - 21² = (29+21)(29-21) = 50*8 = 400

DE =√400 =  20

x = DE  {in Kite, diagonal AC bisect DB. DE = EB}

x = 20

DC² = DE² + EC² = 20² + 99 ² = 400 + 9801 = 10201

DC = √10201 = 101

y =101

In Kite, adjacent sides are equal.

AD = AB = 29

CD = CB = 101

Perimeter = 29 + 29 + 101 +101 = 260

A recreation center charges nonmembers $3 to use the pool and $5 to use the basketball courts. A person pays $42 to use the recr
Andrei [34K]
Let x = times in the pool
Let y = times in the basketball courts

42=3x+5y
x+y=12
Therefore y = 12-x
Subsitute for y
42 = 3x + 5(12-x)
42 = 3x + 60 -5x
Subtract 60
-18 = -2x
9 = x

The person used the pool 9 times.

If AB=48 and BC=22, then AC=?
alexandr1967 [171]

If A, B and C are collinear, then

1) if B is between A and C:

AC = AB + BC

AC = 48 + 22 = 70

2) if C is between A and B:

AB = AC + BC

48 = AC + 22 |-22

AC = 26

3) if A is between B and C:

BC = AB + AC

22 = 48 + AC |-48

AC = - 26 < 0 FALSE

Answer:

if B is between A and C, then AC = 70

if C is between A and B, then AC = 26
