Question

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?

Answer 1

Its not c if that helps

Explanation:

Answer 2

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
`m_X_Y` and
`m_Y_W` respectively

so


`m_X_Y*m_Y_W=-1`


`m_Y_W= (-1)/(m_X_Y)`


`m_Y_W= (-1)/(0.56)`


`m_Y_W= -1.786`

Right answer:
`m_Y_W= -1.786`
