Question

two adjacent angles of a parallelogram Rs 1:2 find the measures of all the angles of the parallelogram​

Answer 1

Answer:

Let us take rhe given ratio be x:2x.

And we know that the sun of adjacent angles of a llgm is 180°.

So , ATQ , x + 2x = 180°.

or 3x = 180°.

or x = 180°/3.

Therefore x = 60°.

So, first angle = x = 60°.

second angle = 2x = 120°

Also, we know that the opposite angles are equal.

Therefore all angles of llgm are 60° , 120°, 60° & 120°.

Answer 2

Step-by-step explanation:

let the ratio be x

1x

2x

=1x+2x= 180 sum of adjacent angle

=3x = 180

=x = 180/3

= x = 60

so 1x= 1*60

= 60

and 2x = 2*60

= 120
