Geometry Application

Section 4.3



Let me see.

I need to find the coordinates of the point (x, y).

To find the x-coordinate, do this:

x = 10•cos (20°)

To find the y-coordinate, do this:

y = 10• sin (20°)

After finding the values of x and y, I can then find the six trigonometric functions of a 20 degree angle by using SOHCAOTOA.

Yes?

 

Yes

 

Thanks. I do my best to do my part per thread.
