Question

The adjacent angels of a paraalleogram are in the ratio 4:5.find the measure of all the angles of the parallelogram.
​

Answer 1

Answer:

We know that adjacent angles are supplementary in a 'paraalleogram'.

so the equation stands like this-

4x + 5x = 180 ( let x be common multiple)

9x = 180

180/9 = x

4x = 4 x 20 = 80 degree

5x = 5 x 20 = 100 degree

We also know that opposite angles are equal in a 'paraalleogram'.

So,

Two angles in it will measure 80 degrees

and

Two will measure 100 degree.

Have a great day ) Hey, i was just kidding about 'paraalleogram'.

Hope you understand the answer and the joke )
