Question

ABCD is a square. find x

Answer 1

<ADB = 45°...... because angles on diagonal of a square are always 45°

Now,

<DOE = 180° - 85° .........linear pair.

<DOE = 95°.

And, <DAB = 90° ......propeety of a square.


Now, in the quadrilateral AEOD,

Sum of all angles = 360°

45° + 90° + x + 95° = 360°

230° + x = 360°


x = 360° - 230°

x = 130°.........●
