Answer: 
Step-by-step explanation:
You have the equation
.
Then, to solve for the variable
from the equation you need:
Make the subtraction of the right side of the equation:
(As the denominators are 1 and
, the least common denominator is
)

Multiply
to both sides:

Add
to both sides:

And finally divide both sides by
:

The measure of FHG is 64°.
V+4 3/4=5 2/5
v+4.75=5.4
v=0.65. Hope it help!
