and s M stands for the slope of m and

s and stands for the slope of end in which

of the following statements must be true and hear the

potential answers Seven his life Okay so what's this question

asking Well we're given a graph featuring a triangle that

looks badly in need of its morning cup of coffee

way And we need to figure out what would happen

if we multiplied the slopes of the three sides of

the triangle together They're no given numbers here Missed a

few letters So what gives Well let's look at the

other information that we are giving problems Says this is

a right triangle And yet there's a little right triangle

symbols So we know the two legs of the triangle

side in inside em are perpendicular ninety degrees member Okay

so what do we know about perpendicular lines Slope wise

Well hopefully remember that the slopes of the perpendicular lines

are always negative Reciprocal sze in other words multiply the

slopes of any two perpendicular lines and you get negative

one like if the slopes or three and negative a

third toe All three terms negative Third is negative one

and it'll be the same with any too negative reciprocal

ls he decide to plug in there lose us with

just negative one time The last side side l were

looking over The answer choices It makes sense that sea

would work because negative onetime side l will always equal

negative side L so yeah we've got her answer and

our triangle friend has finally got his coffee All is 00:01:54.633 --> [endTime] right in the world
