What's the answer to this math question?

<p>Hint: tan θ = (-5)/(-3) = 5/3. How do you find the angle measure of θ?</p>

<p>Please also note, from the data, the angle must be greater than 225 degrees, so you can rule out the first three. To determine with certainty, use rspence’s note.</p>

<p>Since point P is (-3, -5) it means that the right angle trianlge drawn between origin and P will have two legs with measures 3 and 5.
Since you can get all the sides using Pythagoras and you have one angle, which is the 90 degree, you can use some trigonometry to find the rest of the angles.
The sine rule will be used here.</p>

<p>Here’s an explanation of the sine rule in case you are not familiar with it…
