Answer:
A) 23°
Step-by-step explanation:
After observing the diagram shown above, we can see that the circle is places on a straight line labelled as AFG
It is important to note that angles on a straight line (AFG) = 180°
We are given
Angle BFA =61°
Arc EH = 26°
Arc BH = 70°
Angle GFE = unknown. We are to find this angle.
Since the angle on a straight line(AFG) = 180°
Therefore,
180° = Angle BFA + Arc EH + Arc BH + Angle GFE
180° = 61° + 26° + 70° + Angle GFE
180° = 157° + Angle GFE
Angle GFE = 180° - 157°
= 23°
