Question

Lenght of thehypotenuse of a right angled triangle is 61 cm. Its one side is 11 cm. Find the lenght of the other s
ide

Answer 1

Answer:

Step-by-step explanation:

let the hypotenuse be ac, the side of 11 cm be bc and the side to find out be ab.

we know that,

(ab)2 + (bc)2 = (ac)2

(ab)2 + (11)2 = (61)2

(ab)2 + 121 = 3721

(ab)2 = 3721  -  121   = 3600

ab = square root of 3600 = 60

therefore, the other side = 60 cm

Answer 2

Answer:- By Pythagoras Theorem :

H² = P² +B²

61² =P² +11²

√61×61 - 11×11 = P

P =  √3721 -121

P  =  √3600

P  =  60cm
