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°
