20. A rectangle is eight inch long and its diagonal is ten inches. What's the width of the rectangle?
(A) 3 inches
(B) 6 inches
(C) 4 inches
(D) 5 inches

B

Step-by-step explanation:

In this case you would use the pythagoram theorem.

A^2+B^2=C^2

8^2+B^2=10^2

64+B^2=100

subtract 64

B^2=36

square root both sides

B=6

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
