Answer 1

Answer:

100°

Step-by-step explanation:

let us name the fig. first...

/ a for the left most intersection point

/ b for the top most point

/ c for the angle in between 60° and / b

/ o for the centre

/ e for the bottom most

60°- / f

/ oea=80°(given)

Therefore / oef= 100° (linear pair)

/ boc=70°(given)

therefore / coe=110°(linear pair)

angle sum property of a quad. revels that

/ocf=80°

assuming that line bcf is a straight line, by linear pair x= 100°
