The length of side C=16.55(2dp) unit

Explanation:

The sides A=15 ; B=7 and their included angle /_c=pi/2=90^0 are given. This is a right angled triangle of which sides are A and B and hypotenuse is C
Hence by Pythagorus theorm we know A^2+B^2=C^2 or C^2=15^2+7^2= 274 :. C= sqrt 274 =16.55(2dp) unit[Ans]
