(-5x^5)(a) = 25x^7 + 100x^5
<u>+5x^5 +5x^5</u>
a = 25x^7
The trigonometric ratio will be Cos(n)=12/13
<h3>What will be the trigonometry ratio?</h3>
Given is a Right triangle LMN with right angle at M i.e. angle M = 90 degrees.
Given are the sides LM = 15, MN = 36, and LN = 39.
It says to find cos(n) = ?
So opposite side would be LM, adjacent side would be MN, and LN is the hypotenuse.
We know that the cosine ratio is given by :-




Hence the required ratio will be
