using SOHCAHTOA, tan(theta)=opp/adj tan(60)=(x/5),x=5tan(60), x=8.66 or Pythagoras's theorem x^2+y^2=z^2, 5^2+x^2=10^2, 25+x^2=100, x^2=100-25, x=sqrt(75)= 8.66

holy crap lol, okay lets do this using pythag theorem.. step by step now thats too much for me lol. a2+b2=c2 so 5^2+ x^2 = 10^2 right?

OpenStudy (saifoo.khan):

right.

OpenStudy (saifoo.khan):
