Answer:
The answer is 40°
Step-by-step explanation:
Solution
Now,
The Measure of major arc FD = 280°
Thus,
One complete angle measure 360°
Then
 m∠FED = 360 - 180
 m∠FED = 80°
Thus,
 FE = DE ( the same circle Radius)
 ∠EFD = ∠EDF (  opposite angles to equal sides are equal)
Now
Applying angle sum property of a triangle in ΔEFD
 ∠EFD + ∠EDF + ∠FED = 180°
 ∠EFD + ∠EFD + 80 = 180
 2∠EFD = 100
 ∠EFD = 50°
Hence, GF is tangent to the circle and the tangent always make right angles with the radius of the circle.
∠EFG = 90°
∠GFD + ∠EFD = 90°
 ∠GFD + 50 = 90
∠GFD = 40°
Therefore, The measure of the angle GFD is 40°

Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
 = k
 = k     
If v  = 30 and d = 400, then
30( ) = k
) = k
k = 30(20) = 600
Now  = 600
 = 600
If d = 25, then v = 600
 = 600
                          5v = 600
                             v = 120
