Question

two angles are quadrilateral and the other two angle 70 degree and 80 degree?

Answer 1

Solution :

Let p, q , x , x are four angles of a

quadrilateral .

Let p = 70° , q = 80°

we know that ,

p + q + x + x = 360°

=> 70° + 80° + 2x = 360°

=> 150° + 2x = 360°

=> 2x = 360° - 150°

=> 2x = 210°

=> x = 210°/2

=> x = 105°

Therefore ,

Remaining two equal angles are 105° , 105°
