Answer:

In ∆ABC AS C=90°

WE CAN APPLY PYTHAGORAS THEORM

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

(3)^2+(4)^2=(AC)^2

9+16=(AC)^2

25=(AC)^2

AC=√25

AC =5 UNITS

Answer:

AB = 5 units

Step-by-step explanation:

angle C is 90°

ABC is a right angle triangle

hypotenuse is AB

AC and BC are sides

by Pythagoras theorem

 {hyp}^{2}  =  {adj}^{2}  +  {opp}^{2} \\  {hyp}^{2}  =  {4}^{2}  +  {3}^{2}  \\   {hyp}^{2} = 16 + 9 \\  {hyp}^{2}  = 25 \\ hyp \:  =  \sqrt{25}  \\ hyp = 5 \\

therefore AB = 5 units
