24/7
Step-by-step explanation:
cos(theta)=24/25
so draw right triangle
you get the length of each side be
7 24 25
(you must draw a picture)
then the answer would be 24/7
Hi,
You just have to change z^25 to z^24 or z^27.

The given quadratic expression; 5b² -6b -2 is prime because the discriminant is not a perfect square.
<h3>
