Given:
Angle EKH=72°
To find:
The measure of x°
Solution:
The required measure of x° is 66°. (Option B)
We know that the angle made at the centre is double the one formed at the circumference.
So, angle EOH=2(angle EKH)
Angle EOH=2(72°)
Angle EOH=144°
Now, we know that EF=FG=GH.
Since these chords are equal, they divide the angle made at the circle's centre into three equal parts.
We will join OF and OG.
Now, in triangle EOF,
OE=OF (circle's radius)
So, angle OEF=angle OFE=x
Angle EOF=1/3(angle EOH)
Angle EOF=1/3×144°
Angle EOF=48°
Also, angle EOF+angle OEF+angle OFE=180°
Using the values,
48°+x+x=180°
2x=180°-48°
2x=132°
x=66°
Therefore, the required measure of x° is 66°.
