Answer 1

sin45=x/14
14sin45=x
x=9.899
\[x \approx10\]

Answer 2

thank you so much! very impressive!

Answer 3

:) you're welcome :) \[\sin \theta=\frac {opposite} {hypotenous}\]

Answer 4

can you help with 15? i think its 9 but im not sure

Answer 5

\[\tan \theta = \frac {opposite}{adjacent}\]\[equilateral\ \triangle => base \ angles = 60^{o}\]\[=>\tan 60=\frac {x}{6}\]\[6(\tan60)=x\]\[x=10.392\]
