Question

Two opposite angles of a parallelogram are (3x+4) and (5x-2) .find the measure of all the angles of the parallelogram

Answer 1

• Opposite angle of parallelogram are equal.

( 3x + 4 ) = ( 5x - 2 )

3x - 5x = - 2 - 4

- 2x = - 6

x = 3

1 St angle :- 3x + 4 = 13

3rd angle :- 5x - 2 = 13

• Sum of adjacent side of angle is 180.

Let the adjacent ( 2nd angle ) be y

y + 13 = 180


y = 180 - 13


y = 167

• 2 nd angle = 4th angle

2nd angle = 167

4th angle = 167

Answer 2

ANSWER:

=The opposite angles of a parallelogram are equal

=(3x+4)=(5x-2)

=-2x=-6

=x=6+2

=x=3

=1st angle=3x+4=13

3rd angle=5x-2=13

=sum of adjacent side of angle is 180°

=Let the adjacent (2nd angle ) be y

=y+13°=180°

=y=180°-13°

=y=167°

=2nd angle=4th angle

=2nd angle=167°

=4th angle=167°
