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 {ll}^{gm} 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 = \dfrac{230}{2}

= x = 115

The value of all the angles :-

  • 1st angle = 65
  • 2nd angle = 65
  • 3rd angle = 115
  • 4th angle = 115

Thank you ! :D
