Question

plz tell the answer​

Answer 1

Answer:

X=34°

Y=10°

The sum of opposite angles of a parallelogram=180°

120°+6y=180°

6y°=60°

y=10°

Now, we know that sum of all the angles of a quadrilateral =360°

5x+10+120+6y=360

=5x+10+180=360

=5x+190=360

=5x=360-190

=5x=170

=x=170/5

=x=34

Answer 2

Answer:

your answer y = 20°

x =

Step-by-step explanation:

6y° = 120°[Opp. angle are equal of parallelogram]

y° = 120/6

y° = 20°

_________________________

Note:- (5x + 10)°,I am take two times because

we have same two angle in parallelogram.

6y° we already get value of that.

120° + 6y° + (5x + 10)°+ (5x + 10)° = 360°

120° + 120°+ 10x + 20 = 360°

240° + 10x + 20 = 360°

260° + 10x = 360°

10x = 360 - 260

x = 100/10

x = 10°
