Question- The sun of opposite angle of a parallelogram is130°. Find all the angles.
Answer:
angles are = 130° , 50° ,130° and 50°.
Step-by-step explanation:
Given :
opposite angle of a parallelogram is130°.
To find : all angles
Concept used :
- opposite angle of parallelogram are equal
- sum of all the angles of parallelogram is 360°
solution:
Let other two angles be X°
Now, 130+130+X+X = 360°
260+2X= 360
2x= 100
x = 50°
mark my answer as brainliest please ♥️

Answer :
Given :
- The sum of opposite angles of parallelogram is 130°.
Find :
- All the angles of parallelogram.
Solution :
We have,
- The sum of opposite angles = 130 .
- Then the value of both angles 130 ÷ 2 = 65
We know that ,
- The opposite angles of
are equal.
- Sum if its all side is 360°
Now,
- Let the opposite angles be x
Sum of all the angles of a parallelogram
= x + x + y + y = 360°
= 2x + 130 = 360°
= 2x = 360 - 130
= x =
= x = 115
The value of all the angles :-
- 1st angle = 65
- 2nd angle = 65
- 3rd angle = 115
- 4th angle = 115
Thank you ! :D
