a slope parallel to 5/2 is still 5/2 right or would you flip it to 2/5?

jimthompson5910 (jim_thompson5910):

parallel lines have equal slopes

jimthompson5910 (jim_thompson5910):

so it remains 5/2

jimthompson5910 (jim_thompson5910):

if you wanted the perpendicular slope, you flip the fraction AND flip the sign 5/2 ----> -2/5

jimthompson5910 (jim_thompson5910):

but that's extra info for another problem

ok thanks !!!! (:

jimthompson5910 (jim_thompson5910):

you're welcome

OpenStudy (anonymous):

mind helping on another question!! @jim_thompson5910

jimthompson5910 (jim_thompson5910):

ignore the j infront of the arrow !

jimthompson5910 (jim_thompson5910):

can you write the instructions again, things got cut off

jimthompson5910 (jim_thompson5910):

the picture of the triangle shows up fine though, so that's good

OpenStudy (anonymous):

if angle JKM=15x-48 and angle L=5x+12 and angle m=40 find angle MKL

jimthompson5910 (jim_thompson5910):

thanks

OpenStudy (anonymous):

no problem

jimthompson5910 (jim_thompson5910):

we're essentially given these 3 angles |dw:1374354069612:dw|
