Best ResponseYou've already chosen the best response.0\[AB=AD+DB\] \[\cos(60°)=\sin(30°)=\frac{AD}{14}\] \[\sin(60°)=\cos{(30°)}=\frac{DC}{14}\]

Best ResponseYou've already chosen the best response.0Do I then need to use the sin and cosine formula to figure the rest out?

Best ResponseYou've already chosen the best response.0actually you can work out angle DCB with a trig identity, because be know two of the sides, and then use another trig identity to find DB

Best ResponseYou've already chosen the best response.0you dont know the values of sin 30=cos60? you must remember theses if you dont remember you can use a calculator

Best ResponseYou've already chosen the best response.0\[\sin60°=\cos30°\] is a little bit tricker on a calculator, because the value given is irrational but you can square the output 0.86602540... 0.86602540...^2=0.75=3/4 so \[\sin60°=\cos30°= \sqrt{\frac{3}{4}}=\frac{\sqrt3}2\]
