Find AM in the parallelogram if PN = 12 and AO = 3

OpenStudy (anonymous):

OpenStudy (anonymous):

@chels1226 digonals bisect each other so AM=AO=3:)

OpenStudy (anonymous):

so its 3 ? (:

OpenStudy (anonymous):

yup:)

OpenStudy (anonymous):

thank you! can you help with another one?

LMNO is a parallelogram. If NM = x + 17, and OL = 3x + 5, find the value of x, and then find NM and OL.

OpenStudy (anonymous):

@chels1226 opposite sides of a parllelogram are equal so NM=OL x+17=3x+5 2x=12 x=6 so NM=x+17=17+6=23 :)

In the figure, the horizontal lines are parallel and AB = BC = CD. Find JM. The diagram is not drawn to scale

@chels1226 parllel lines make equal intercepts so ML=LK=KJ=6 MJ=ML+LK+LJ=3*6=18 :)

OpenStudy (anonymous):

so the answer is 18 ?

OpenStudy (anonymous):

yup:)

OpenStudy (anonymous):

@Aperogalics In the figure, the horizontal lines are parallel, and AB = BC = CD. Find KL and FG. The diagram is not drawn to scale.

OpenStudy (anonymous):

solving ur homework....lol:)

OpenStudy (anonymous):

sorry ): im not very good at this . lol

OpenStudy (anonymous):

no prob. i personally think u r good just u need the direction so if 3lines are parllel and equidistant then intercept by a line are equal|dw:1352989955131:dw| so here AB=BC DE=EF GH=HI IJ=JK

OpenStudy (anonymous):

SRY IJ IS NOT EQUAL TO JK JK=KL :)

OpenStudy (anonymous):

A. KL = 5.7; FG = 7.2 B. KL = 7.2; FG = 5.7 C. KL = 7.2; FG = 7.2 D. KL = 5.7; FG = 5.7

(B) :)

Find values of x and y for which ABCD must be a parallelogram. The diagram is not drawn to scale.

OpenStudy (anonymous):

digonals bisects each other so 2x-2=x+2 and 5y-8=y+24 x=2+2 5y-y=24+8 x=4 4y=32->y=8 :)

OpenStudy (anonymous):

In the rhombus, angle 1 = 6x , angle 2 = x+y , and angle 3 = 9z. Find the value of each variable. The diagram is not drawn to scale.

OpenStudy (anonymous):

OpenStudy (anonymous):

digonals bisect at 90 so 6x=x+y=9z=90 x=90/6 z=90/9 x=15 z=10 x+y=90 y=90-15=75 :)

OpenStudy (anonymous):

In the rhombus, angle 1= 168/ What are angle 2 and 3? The diagram is not drawn to scale
