Question

In triangle ABC, if angle C is 90 degree and AB=5, BC=4, find AC.​

Answer 1

Answer:

3 is the answer

hope it helps u

Answer 2

Given that,

AB=5cm hyp

BC=4cm opp side

C=90°

AC=? Adj side

Pythagoras theorem states that

(hyp)2= (adjacent side)2 + (opposite side)2

5×5= 4×4 + (AC)2

25= 16 +(AC)2

transpose 16 to LHS

25-16 = (AC)2

9 = (AC)2

3 = AC as the root of 9

is 3.
