For triangle XYW, the slope of WX is , the slope of XY is 0.56, and the slope of YW is . Which statement verifies that triangle WXY is a right triangle?

Respuesta :

If lines through XY and YW form a 90° angle, so that Y is a right angle, 

then the product of the slopes of the lines through XY and YW must be -1

let the slopes through X,Y and Y,W be [tex]m_X_Y[/tex]  and  [tex]m_Y_W[/tex] respectively 

so 

[tex]m_X_Y*m_Y_W=-1[/tex]

[tex]m_Y_W= \frac{-1}{m_X_Y} [/tex]

[tex]m_Y_W= \frac{-1}{0.56} [/tex]

[tex]m_Y_W= -1.786 [/tex]

Right answer: [tex]m_Y_W= -1.786 [/tex]
