Question

The opposite angles of a parallelogram are (4y+5)°and (3y+15)°. Find all the angles of the parallelogram.​

Answer 1

Answer:

$4y + 5 = 3y + 15 \\ 4y - 3y = 15 - 5 \\ y = 10$

the angles are 45°

and (360° - 2×45°) / 2

= 270°/2 =135°

Answer 2

Answer:

Step-by-step explanation:

we know that in a parallelogram

opposite sides are equal

adjucent add up to 180

(4y+5)=(3y+15)

= 4y-3y=15-5

=y=10

so, (4y+5)=(40+5)=45

(3y+15)=(30+15)=45

therefore let adjucent sides be x

ATQ

45+x=180

=x=180-45

=x=135

the angles are

L1=45

L2=135

L3=45

L4=135

hope this helped
