Given a right triangle with base, b and height, h with the angle opposide side h as θ.
The area of a triangle is given by

But,

Therefore, the area of the triangle in terms of <span>b and θ only is given by

Answer:
(4x3-6x) + (8x-12)= 2x
(4x3+8x) + (-6x2-12)= 2(2x-3) (x^2+2)
Step-by-step explanation:
All you have to do is simplify.
A statement also know as an axiom which is taken to be true without proof.
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
