Question

in the given figure AB||CD angle EAB=84 degree and angle ECD=126 degree. Then find the value of x

Answer 1

Answer:

Step-by-step explanation:

CD AND AB are parallel

therefore making a line perpendicular from CD to AB will make a 5 sided polygon (pentagon)

Sum of all exterior angles of any polygon is 360

360/5=72 (exterior angle of regular pentagon)

one angle of regular pentagon=180-72=108

sum of all angles of pentagon=108*5=540

therefore

x+135+130+90+90=540

x+265+180=540

x+445=540

x=540-445

x=95

therefore the value of x is 95°
