Question

find x in the following figure ​

Answer 1

Answer:

x=20

Step-by-step explanation:

sum of supplementary angles = 180

sum of interior angles =360

so,90+90+120+y=200+y

200+y=360

y=360-200

= 160

x+y=180

x+160=180

x=180-160

=20

Answer 2

Answer:

Answer=20°

Step-by-step explanation:

sum of supplementry angles=180°

sum of interior angles=180°

therefore,

90°+90°+120°+y°=200°+y°

200°+y°=360°

y°=360°-200°

=160°

x°+y°=180°

x°+160°=180°

x°=180°-160°

x°=20°
