Answer:
Step-by-step explanation:
Notice that .
The diagram already marks , so we just need to find
.
and
are vertical angles, which means they are equal in measure.
Therefore,
Since there are on each side of a line, we have the following equation:
.
Plugging in , we have:
.
Therefore,
.
Given :
∠ABF = ( 7x + 20 )°
∠FBC=(2x - 5)°
∠ABC= 159°
To Find :
The value of x .
Solution :
Assuming B the center of a circle .
So , all three given angles must be added to 360° .
Therefore , the value of x is 20.67° .
Hence , this is the required solution .
