Triangle LMN is similar to triangle PQR, and the hypotenuses of the triangles both lie on line X.
Mice21 [21]
Answer: choice C) -2/3

The line X is completely straight meaning that the slope of line X is the same no matter which two points you pick. Since we're given that line X has a slope of -2/3 through the points (-7,6) and (-4,4), this also applies to the portion from (-1,2) to (5,-2)

4. Cross multiply (10•6) (15•n) 15n=60 you do the opposite operation so instead of multiply 15•n you divided 15 from n. And what u do on one side u do on both. So divide 15 from 60 and u get 4.

x + 51 + 51 = 180

x = 180 - 102

x = 78º

y + y + 110 = 180
