Question

ABCD is a quadrilateral. Find x if A=x,B=80°,c=50°,D=120°​

Answer 1

Answer:

A+B+C+D =360°

THEREFORE ,

X+80+50+120=360

X=360-250

X=110°ANS

Answer 2

Step-by-step explanation:

Since the sum of angles of a quadrilateral is 360 degree so 120+80+50+x=360

so 250+x =360

x=360-250

=110 degree

<A =110 degree
