The value of angle EFH would be =30°
How to calculate the value of the missing angle?
To calculate the value of the missing angle, the following steps should be taken as follows:
Line FH is the angle bisector of <F
Therefore,
<GFH = <HFE
6p = p+25°
Bring like terms together;
25 = 6p-p
25 = 5p
Therefore ,< EFH = 5+25 = 30°
p = 25/5
= 5
