In respect to angle 35 where is x and side 18? Opposite, adjacent or hypotenuse?

3. anonymous

?

4. anonymous

What have you learned so far that will help us solve this problem?

5. anonymous

sine cos tan

6. anonymous

sin=SOH cos=CAH tan=TOA where O=opposite A= Adjacent H=Hypotenuse In respect to angle 35 side 18 and x are opposite and the hypotenuse O and H ok? Tell me which one uses both O and H?

7. anonymous

sin

8. anonymous

Yes $\sin(35^o)=\frac{opposite}{hypotenuse}$$\sin(35^o)=\frac{18}{x}$${x*}\sin(35^o)=18$ $x=\frac{18}{\sin (35^o)}$

10.3

10. anonymous

no 31.3

11. anonymous

Yes you are correct

12. anonymous

Remember sin=SOH cos=CAH tan=TOA
