Answer:
B and D
Step-by-step explanation:
First method :
All angles of a quadrilateral sums to 360 degrees
A + B + C + D = 360
=> 5x^2 + 36x - 336 = 0
=> x = 6 or x = - 56/5 [It gives negative value of angles]
So, A = 58, B = 109, C = 122, D = 71
Second method :
Sum of opposite angles of a quadrilateral inscribed in a circle is 180 degrees
A + C = 180
=> x = 6
So, A = 58, B = 109, C = 122, D = 71
