Question

The measue of two adjacent angle of a quadrilateral are 85° and 115° the other two angle are equal find the measure of each angle

Answer 1

le the other angle = x
115+85+x+x =360 (angle sum p .)
200+2x= 360
2x = 360-200
x = 80

Answer 2

Hey friend !!

Here is your answer..

--------------------------------------------------

The two angles are 85° and 115°.

And the other two angles are equal.

So let the first angle be x.

Since , the two angles are equal.

Therefore , there sum will be 2x.

Now, by angle sum property of quadrilateral.

We get,

==> 360° = 85° + 115° + 2x

==> 360° = 200° + 2x

==> 2x = 360° - 200°

==> 2x = 160°

==> x = 80°

Hope it helps.
