Question

if A(4,3) B(-1,y) and C(3.4) are the vertices of a right angled triangle ABC angle A=90°then find the value of the y​

Answer 1

Step-by-step explanation:

SOLUTION:-

As this is a right angle triangle, then

AC^2+AB^2=BC^2

By using distance formula we get,

[{(4-3)^2}+{(3-4)^2}]^2+[{(4+1)^2}+{(3-y)^2}]^2=[{(3+1)^2}+{(4-y)^2}]^2

By solving this we get the value of y
