Question

Angle ABC = 90°, AB = 8 cm and BC = 5 cm.

Calculate the length of the rod AC.
Give your answer to one decimal place.

Answer 1

Answer:

root(89) is your answer.

Answer 2

Answer:

THE ANSWER IS  UNDER SQRT 89

Step-by-step explanation:

WE KNOW THE SIDE AND BASE OF THE RIGHT ANGLED TRIANGLE . SO WE CAN FIND THE HYPOTENUSE BY USING PYTHOGORAS  THEOREM .

( AC ) ^ 2 = ( AB )^2 + ( BC )^2

( AC )^2 = ( 8 )^2+ ( 5 )^2

( AC )^2 = 64 + 25

( AC )^2 = 89

AC = UNDER ROOT 89

HENCE , THE LENGTH OF ROD AC IS sqrt 89
