Answer:

45°

Step-by-step explanation:

//Opposite angles of parallelogram are equal.

4y + 5 = 3y + 15

y = 10°

The angle is 4*10+5 = 45°

Answer:

Answer:45° and 130°

Given:

A llgm ABCD in which two opposite angle of llgm are (4x+5) and (3y+15)

To find:

All the angles of llgm

Solution:-

As opposite sides of llgm are equal

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

4y-3y=15-5

Y=10

Then,

(4x+5)=4×10+5

=45

(3x+15)=3×10+15

=45

Now Sum of all the angles of a llgm is equal to 360°

45°+45°+x+x=360°

90°+2x=360°

2x=270

x=135°

<A=45°,<B=135°,<C=45° and <D=135° ★Verification

Sum of the angles of llgm=360°

45°+135°+45°+135°=360

360°=360°
