Just try them quickly, there's a more formal method, but it'd be much more complicated for such a simple problem. They want only even numbers. You can quickly see 10 x 12 = 120 is smaller than 224 and 18 x 20 = 360 is too big. You're left with 12 x 14, 14 x 16, etc...

Well, the only thing I can see "lacking" in the definition is if the intersection P is actually also one of the A,B,C,D points. So you could just say ""If line AB and line CD intersect at point P such that P is different from A, B, C or D, then angle APC ...

**trig**

Cot (theta) is just 1/(Tan(theta)). So we have 0.05 = 1/(Tan(theta)) And thus, by multiplying both side by Tan(theta), we have : 0.05 x Tan(theta)= 1 So Tan(theta)= 1/0.05 = 20 Tan (theta) = 20
