= 
= 
15
We require the denominators to be like before we can add.
factor x² - 4 as a difference of squares
x² - 4 = (x + 2)(x - 2)
Expressing as
+ 
multiply the numerator/denominator of the first fraction by (x - 2)
=
+ 
Expand and simplify the numerators, leaving the denominator

Answer:
angles in a triangle add up to 180°
5:12:13 = 30
180 ÷ 30 = 6
