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:
(1/5)x-5.4=y
Step-by-step explanation:
mx+b=y
m=(1/5)
(-8,-7)=(x,y)
(1/5)(-8)+b=(-7)
-1.6+b=-7
b=-5.4
(1/5)x-5.4=y
Translation does not affect length.
So the length of E'F' is 5 units.

brainliest pls :)
72 m is the surface area because you multiply L × W × H, which is 6 × 4 ×3 = 72
