Answer:
m<HGF = 45
Step-by-step explanation:
This picture shows an inscribed angle. It is made of 2 chords that connect on the vertex.
An inscribed angle is equal to half the arc. It is the arc that the angle makes. In this case it is the arc HF. So, to find the answer you would divide the length of arc HF by 2.
90/2=45
