Answer 1

Answer:

BY PYTHAGORAS THEROEM

H^2-S1^2=S2^2

25^2-20^2=S2^2

625-400=S2^2

225=S2^2

S2=15 cm

Answer 2

Answer:

15 cm

Step-by-step explanation:

(hypotenuse)2= (one side)2+ (second side)2

(25)2 = (20)2 +( second side )2

(25)2 - (20)2 =( second side)2

625-400 = ( second side)2

225= (second side)2

Taking square root

second side= 15 cm

The length of other side is 15 cm.
