Prove that a triangle with sides x cm, 2x cm and root5x cm form a Right-angled triangle. ​

Step-by-step explanation:

x+2x+3x=180

6X=180

x=180/6

x=30

again

2 x=2×30

=60

3×=3×30

=90

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
