Helpp

What is the length of stack H D with bar on top when BH = 20 in., BC = 12 in., and DC = 14 in.? Round your answer to the nearest tenth of an inch.

Answer 1

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.
