Question

in a right angle triangle the hypotenuse is equal to20cm and the ratio of other two sides is 4:3 then find the lebgth of other two sides

Answer 1

I hope it will help you

Answer 2

Let the other two sides be 4x and 3x

According to Pythagoras theorem

hypotenuse sq=sum of sq of other two sides

20 sq = (4x)sq + (3x) sq

400 = 16x sq + 9x sq

400 = 25 x sq

x sq = 400/25

x = root over 400/25

x = 20/5

x = 5

Therefore other sides 4x=4*5=20 and

3x=3*5=15
