Answer 1

Answer:

first ques answer angle 3 and 4 are 119°

9) x=120° by using cylcic quadrilateral and linear pair property

10) angle ACB is 50°

angle OAB and angle OBA are same becayse radius of circle is OA and OB, soby isoscles triangle OBA is 40°

so therfore angle AOB is 100° and by using circle property inscribed angle is half the measure of central angle so it is 50°
