interior angles of a parallelogram are 40x and 50y.write a linear equation which satisfies this data.also draw a graph which satisfies this data.
Anonymous:
but cant add the graph
ok
so,i cant post the ans.:P
atleast you can write an equation
is that enough?
yes
ok,
done
check it
and ask doubts if any

we know,in a llgm opp.ang. are equal
so, the angles will be- 40x,50y,40x,50y
according to ang.sum property of a quadrilateral,
40x+40x+50y+50y=360
i.e. 80x+100y=360
now substitute the values for x and find the y's .hence we can get the coordinates to draw the graph

can u plss pick it as the best?
yes
thanks

In a parallelogram the opposite angle are equal
sum of the angles=360
the angles will be 40x,40x,50y,50y
40x+40x+50y+50y=360
80x+100y=360
20(4x+5y)=360
4x+5y=18
sum of the angles=360
the angles will be 40x,40x,50y,50y
40x+40x+50y+50y=360
80x+100y=360
20(4x+5y)=360
4x+5y=18
