Question

in triangle abc, angle b=90 AB=2x+3 BC=x+2 AC=3x-1 then find x​

Answer 1

The figure will be a right-angled triangle. (A triangle in which one angle=90 degrees is called a right angled triangle.)

Let's recall Pythagoras Property,

(AB)^2+(BC)^2=(AC)^2

(2x+3)^2+(x+2)^2=(3x-1)^2

4x^2+x^2+4=9x^2

5x^2+4=9x^2

4=9x^2+5x^2

4=14x^2

x^2=4/14

x= Square root of 4/14

x=2/7

Hope this is correct
