2. If AABC, ZA = °, ZB = (3x) ° and ZC = y °. If 3y-5x = 30. Show that it is a right angled triangle.

In ABC the /_ A= x@ , /_ B= 3x@ and /_ C= y@ . If 3y-5x=30 then prove that the traingle is right angled.

In a ABC,quad /_A=xo,quad /_B=3xo and /_C=yo* If 3y-5x=30, prove that the triangle is right angled.

In a Delta A B C ,\ \ /_A=x^o,\ \ /_B=3x^o and /_C=y^o . If 3y-5x=30 , prove that the triangle is right angled.

Suppose x and y are any two natural numbers. If x^2-y^2, 2xy and x^2+y^2 are three sides of a triangle then show that it is a right angled triangle

in the triangle ABC , /_A=x^@,/_B=3x^@,/_C=y^@ . if 3y-5x=30 then prove that the triangle is right angled.

in the triangle ABC,/_A=x^(@),/_B=3x^(@),/_C=y^(@) .if 3y-5x=30 then prove that the triangle is right angled.

3x + 5y = 34.5x + 3y = 30

Show that the lines x-7y-22=0, 3x+4y+9=0 and 7x+y-54=0 form a right angled isosceles triangle.
