Question

In the accompanying diagram, ABCD is a rectangle. if DB = 26 and DC = 24, find BC

Answer 1

Answer:

by Pythagoras theorem because dbc forms right angled traingle

db^2=dc^2+bc^2

(26)^2=(24)^2+bc^2

(26)^2-(24)^2=bc^2

676-576=bc^2

√100=bc

bc=10

so bc measures 10cm

hope you got the answer !!!
