We will use Pythagorean Theorem:
HC^2=20^2-12^2=400-144=256
HC= $√(256)$ =16
HD^2=16^2-14^2=256-196=60
HD= $√(60)$ =7.7459
Answer: HD=7.7 in.

A wooden board 100 centimeters long is cut into two pieces.One piece is 16 centimeters longer than the other. What are the lengths of the two pieces?

Answers

legnth are x and y
x+y=100

one is 16 more than other
x is 16 more than y
x=16+y

x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42

sub back
x=16+y
x=16+42
x=58

the legnsh are
42 cm and 58cm

One piece is 66 cm and the other piece is 34 cm
