There is only 2 available spots and 50% chance of winning. Answer quickly!
I will be choosing 1 random person.

Step-by-step explanation:

Law of Cosines

If A, B, and C are the measures of the angles of a triangle and a, b, and c are the lengths of the corresponding sides, then the following applies:

a^2 = b^2 + c^2 - 2bc cos A

b^2 = a^2 + c^2 - 2ac cos B

c^2 = a^2 + b^2 - 2ab cos C

The Law of Cosines is true for all triangles.

Radians to degrees conversion:

=

Circumference of a circle:

the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.

To convert radians to degrees, the key is knowing that 180 degrees is equal to pi radians. Then multiply the measurement in radians by 180 divided by pi. For example, pi over 3 radians would be equal to 60 degrees.

C=2pir

pi is 3.14

your answer is the frist one

hop i
