Question

the unequal angles of a parallelogram are in the ratio of 7:3.Find all the angles of a parallelogram

Answer 1

Let the ratio be x. Then, it will be 7x and 3x.

We know that the sum of angles of a //gm is 360°.

So that,

7x +3x=360°

10x=360°

X= 36.

Hence the unequal angles are :-
7x = 7×36= 252°

And, 3x = 3× 36 =108°.

Hope its help you.

And good morning. Have a good day.

Answer 2

sum of adjacent angles of parallelogram is 180°.
⇒ 7x+3x = 180 
⇒10x=180
x = 18
7x=126°
3x =54°
all the angles are 126°,126°,54°,54°.
because frontier angles in parallelogram are equal
