Question

Quadrilateral ABCD is parallelogram, If angle A=3x and angle C =120 then find the value of x -?.

Answer 1

Hi Mate!!!!

//gm :- Opposite Angles are equal.

And



Sum of all the angles = 360


So,. 3 x + 3 x + 120 + 120 = 360


6 x = 360 - 240


6x = 120

x = 20.


!!!!! Have a great day!!!!!

Answer 2

In a qudralateral adjacent angles sum is 180 degree. so A+C=180=>A=180-C=>3x=60=>x=20
