Answer:

C (circumference) =2×π×r

we've got a 30-60-90 triangle

which means 9=d√3, d=5.19 exact inches

or ≈5.20 inches

d=2r, r=5.20÷2≈2.60 inches

C=2×3.14×2.60≈16.328

Answer:

1. 53

2. 20

3. 37

4. 29

Step-by-step explanation:

Since your trying to find the hypotenuse you equation is...

1. 28^2 + 45^2 = C^2

784 + 2025 = C^2

Square Root 2809= C^2

C=53

So after you square root 2809 you get 53.

2. 12^2 + 16^2 = C^2

144 + 256 = C^2

Square Root 400 = C^2

C=20

So after you square root 400 you get 40.

3. 12^2 + 35^2 = C^2

144 + 1225 = C^2

Square Root 1369 = C^2

C=37

So after you square root 1359 you get 37.

4. 20^2 + 21^2 = C^2

400 + 441 = C^2

Square root 841 = C^2

C=20

So after you square root 841 you get 29.

nataly862011 [7]

Answer:
SAS

Explanation:
In triangle ABC:
a would be the side opposite to angle A
c would be the side opposite to angle C

Combining the given, we would fine that we have the measures of two of the sides and the measure of the angle included between them.
This means that we have SAS information.

Check the attached image for visual illustration.

Hope this helps :)
