Question

In the figure o is the center of the circle find the value of x and 2x

Answer 1

Answer:

hey dear here's your answer...

we know according to circle concept ,

we know according to circle concept ,angle CAD = angle CBD

so,

angle CBD=x

also line BC contains center of circle hence triangle CDB is right angle triangle.

hence,

angle CDB= 90 degree

now

we know ,

sum of all angles of triangle is equal to 180 degree .

so,

angle BCD +angle CBD +angle CDB=180

2x + x +90 =180

=> 3x=180-90

=> x=90/3

x=90/3=> x=30 degree

hope it's helpful for you,..
