Question

in the given figure, AB is the diameter of a circle with center O. if ​

Answer 1

Answer:

x=27.5

Step-by-step explanation:

OC and OA are the radius of circle

then OC=OA

AB as a st.line. angle AOC=180-55=125

in triangle AOC

angle A=angle C

equal sides of opp. angle s are equal

sum of angles of triangle is 180

x+x+125=180

2x=180-125

2x=55

x=55/2

x=27.5
