Where the picture i cant see nun i wana help
Answer:
4.4mm
Step-by-step explanation:
Circumference of circle
2 Pi r
Diameter of coin = 22mm
Therefore the radius = 11mm
Therfroe the outer edge (circumference)
= 2 Pi r
= 2 x Pi x 11
=69.11mm
For the inner edge
Diameter = 5
Radius = 2.5
Therefroe inner edge (circumference)
= 2 Pi r
= 2 x Pi x 2.5
= 15.7mm
The difference is
69.11 - 15.7
=4.4mm

Answer:
ED = 4
Step-by-step explanation:
A & B) Triangles FGD and DGE are similar. Set <DFG to x. We can say that m<DGF, m<DGE, and m<EDF are 90 because they are right. Using triangle angle sum theorem in triangle DEF, we can say that m<DEG = 90 - x. And we can use it again to say in triangle FGD to say m<FDG is also 90-x. From AA we can say the triangles FGD and DGE are congruent.
C) In addition to the two triangles above, triangle FDE would also be congruent due to AA. We can write the following equations using the properties of similar triangles:
DGE FDE
EG = ED*y --> 2 = ED*y
ED * 1/y = EF --> ED * 1/y = 8 --> ED = 8y
We can substitute:
2 = 8y^2
1/4 = y^2
y = 1/2
This means ED = 8y = 8(1/2) = 4 --> ED = 4
