Answer:
cos K = 12/13
Step-by-step explanation:
cos theta = opposite side/ hypotenuse for a right triangle
cos K = 12/13
I do believe that the answer to your question is 60%
X^2-5x+5x-25 (multiply (x-5) with (x+5))
X^2-25 ( -5x+5x =0)
X=3.5 add 10 and divide by 8
you can't factorize it in rational numbers
