Question

in a quadrilateral angle d=120,c=x,a=85,b=105​

Answer 1

Answer:

ans = 50 digress

Step-by-step explanation:

a+b+c+d= 360 digress

a+b+d+=310 digress

c= 360-310=50

Answer 2

We know that the angles of quadrilateral sums up to 360°

120+85+105+x = 360

225+85+x = 360

310 +x = 360

x = 360-310 = 50
