1.7b + 4.5k is the simplified equation. Is that the answer you were looking for?
Step-by-step explanation:
Answer:
The radius would be 4.8
Step-by-step explanation:
The circumerfence of a circle can be found use the equation C=2
r. So since we are given the circumerce we need to rearrange the eqaution to it looks like
=r. when we do this out we find that the radius equals 4.8.
The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.
cos A =
