Question

one angle of a parallelogram is three times the other . what are the measure of angles of this parallelogram

Answer 1

According to given sum,

Let one angle of the llgram be x.

And another angle will be 3x.

So, we know that

Sum of all angles in the llgram is 360.

=> x+x+3x+3x = 360

=> 8x=360

=> x=45.

Another angle => 3×45 =135.

so, The angles of the parellelogram are

45 ; 45 ; 135 & 135.

:-)Hope it helps u.

Answer 2

second angle be x
then,first angle=3x
(first first and third angle are equal because they are alternate angles)
second and fourth angle are equal because they are alternate angle
some of parallel ogram=360
according to question
3x+x+3x+x=360
8x=360
x=360/8
=45degre
first and third angle are 45
2nd and 4th angle are 180-45
=135 degree
