Question

two adjacent angle of a llgm are 2y​

Answer 1

Answer:

adjacent angles are of 90 degree

Step-by-step explanation:

adjacent angles of a parallelogram are supplementary.

.......because they are interior angles.

hence,2y+2y=180

4y=180

y=180/4

y=45

angles are 2y =2×45=90

Answer 2

Answer:

86°

Step-by-step explanation:

2y+10+3y-40=180°

then y=42°

and largest angle is94°
