I don't know how to do the last problem, sorry.

You are trying to find the angle at point F. Line AB and DF are parallel.

∠B is the same as∠C, so ∠C = 120°

A straight line is 180°. To find the other angle of the triangle, you do this:

120 + ? = 180

? = 60°

Now that you know 2 of the 3 angles, you can find angle F.

60 + 33 + ∠F = 180

∠F = 87°

What is the sum of the terms of the series (−1) + (−2) + (−3) + . . . + (−10)?
Murrr4er [49]
You can solve this problem by using the Gauss method. The Gauss method is a method where you can add the first and last numbers together, and then multiply by how many times that appears. Here, the sum of the first and last number is -11. In this sequence, it would appear ten times (since there are ten terms and the terms are used twice in every eleven). -11 * 5 is -55, so that means the answer to this question is -55.
