C) 12V2
12^2 + 12^2 = c^2
144 + 144 = 288
V288 = 12V2
Show that the angles A and B are congruent
Answer:

Step-by-step explanation:
The diagram of the sled kite is attached below.
The central part of the kite is square.
We know by the property of a square that all its angles are congruent and equal to 90 degrees.
Therefore:

Angles A and B are congruent.
Answer:
The radius is approx. 7.5
Let me know if it helps or if I got anything wrong!
Step-by-step explanation:
To find the circumference, you need to multiply the diameter by pi (3.14)
And for vice versa, just divide.
Since we don't know the diameter nor radius, we need to divide the Circumference (C) by pi (3.14)
47/3.14=14.968
Which is rounded up to 15.
We have now found the diameter.
We also know that the radius is half of the diameter
15/2=7.5
number 1 is wrong instead of 15 its 25, number 2 is correct.
