rewona [7]

Answer:

Yes there is enough information to find both triangles DEF and DHG are congruent.

Both the triangles are congruent by SAS theorem of congruence.

Step-by-step explanation:

Lets have a look to both of the triangles.

And mention what are the given information in our question.

We have \triangle DEF and  \triangle DHG.

Where

  • FD = DG
  • ED = DH

And we can see that \angle FDE = \angle HDG (Vertically opposite angles).

So we have two sides equal and an angle between the two are equal.

Then we can say that through SAS property of congruence \triangle DEF and  \triangle DHG are congruent  \triangle 's

A circular gift has a 4.75 inch radius. Ilyssa wants to wrap a ribbon that costs $0.50 per inch around the gift. How much money
ollegr [7]

Answer:

$14.93

Step-by-step explanation:

If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.

Total cost=circumference* cost per inch

Circumference of a circle is given by

C=2\pi r

Where r is radius. Substituting 4.75 inch for r then

C=2\pi\times 4.75=29.857142857142\\C\approx 29.86 inch

Cost=29.86*0.50=$14.93
