Answer:
2n
Step-by-step explanation:
All of the trigonometric functions of an angle θ can be constructed geometrically in terms of a unit circle centered at O. Given that:
Sine function
being
Cosine function
being
We will demonstrate the identity above. First of all, we need to square each equation, so:
Adding these two equations:
But as shown in the figure, using Pythagorean theorem
is always equal to 1, then:
The relation to right triangles is that:
<span>The hypotenuse is always equal to 1
</span>The opposite side is equal to
The adjacent side is equal to
C is the answer because whatever you start with, will become the conclusion; and whatever you end with would be the educated guess (hypothesis).
312* 17.5= 5460.00
134*19=2546
2546+5460= $8,006.00
