Point P(-3,4) is on the terminal side of an angle theta. Which of the following is the exact value of cos theta?

Therefore,

Step-by-step explanation:

Unit Circle:

In mathematics, a unit circle is a circle with a unit radius. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in coordinate System.

So the coordinate of point P on the circle is given as,

Here,

Given:

P(-3,2)

So if Radius is one unit i.e r = 1 then on Comparing we get

∴

Therefore,

Step-by-step explanation:

Area of triangle=sume of all sides.

=A+B+C

=1.75+1.45+1.95

=5.15
