Question

in the figue o is the center of the circle, find a+c

a.) b
b.) 2b
c.) 180 - b
d.) 360 - b
3.) 360 - 2b

​

Answer 1

Answer:

a)

Step-by-step explanation:

angle at o made center is double to the angle made by the same arc at other parts the circle

so

the reflex angle of O will be 360-2b

since angle at other part is b

so now add all the angles in the quadrilateral

a+b+c+360-2b=360

a+c-b=0

a+c= b
