Question

How do I calculate the angles of a parallelogram if the acute angel 30'

Answer 1

do u mean that one of the given angle is 30 degrees ??

Answer 2

yes

Answer 3

okay then as in a parallelogram... oposite angles are equal therefore .. two of the angles of the parallelogram would be 30 degree...
now let the unknown angle be x...
and since
in a parallelogram opposite angles are equal
and all the angles add upto 360
therefore

2x + 60 = 360
2x = 300
x = 150 degree..

so.. the angles of the parallelogram are... 30 degree , 150 degree , 30 degree and 150 degree...

Answer 4

so do u want me to explain it to u in more easy way ??

Answer 5

yes plz

Answer 6

alright then..

Answer 7

i have drawn a parallelogram with one angle as x...

and since in a parallelogram opposite sides are equal therefore u could see the labelling so done....

is it clear till here ??

Answer 8

yup

Answer 9

so do u know what is the sum of the internal angles of a quadrilateral?

Answer 10

amm nope

Answer 11

anywayz... now put the sum of the angles of this parallelogram as 360
i.e. x + x+30 + 30 = 360
=> 2x + 60 = 360

taking 60 to the Right Hand side..
then it gives us
2x = 360 - 60
i.e. 2x = 300
now x = 300/2 = 150

and hence u get ur unknown angle..:D

Answer 12

ok so the obtuse angles are 150

Answer 13

yes...:D...

Answer 14

oo ok thanks a lot realy c:

Answer 15

mention not...:D.
it feels great when we explain someone something...:D

Answer 16

lol ya
