sin30= 1/2 and cos 30= \[\sqrt{3/2}\]
anonymous
  • anonymous
now solve \[1/2 +\sqrt{3/2}\]

It says in the back of the book that its \[1+\sqrt{3}/2\] but idk understand how they got the radical

from the unit circle

so, 1+\[\sqrt{3}/2\] is the answer

its just simple.since they have same denominator, you just add the numerators
