Dimension counting via incidence varieties
Quick description
There are many situations in algebraic geometry in which one wishes to compute dimensions of various spaces, such as the space of all lines contained in a given surface in projective space. One
approach to doing this is via so-called incidence varieties.

Let $X\subset\mathbb{P}^N$ be a non-degenerate smooth complex projective variety (manifold for short). Recall that $X$ is called prime Fano if $Pic(X)=\mathbb{Z}\langle \mathcal{O}(1)\rangle$ and if
the anticanonical divisor $−K_X$ is ample.

How do I find the angles of an isosceles triangle whose two base angles are equal and whose third angle is 10 less than three times a base angle?
Since you're looking for the measurement of the angles, you can begin this problem by assigning a variable to each angle. So let's call the two base angles
and the third angl... | {"url":"http://www.cliffsnotes.com/cliffsnotes/math/how-do-i-find-the-angles-of-an-isosceles-triangle-whose-two-base-angles-are-equal-and-whose-third-angle-is-10-less-than-three-times-a-base-angle","timestamp":"2014-04-20T08:21:41Z","content_type":null,"content_length":"86650","record_id":"<urn:uuid:9854ceb0-c6ca-421e-... |

Probably Overthinking It
