Answer
A.
10.3
B.
31.4
C.
10.7
D.
31.8

Answer 1

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

Answer 2

?

Answer 3

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

Answer 4

sine cos tan

Answer 5

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?

Answer 6

sin

Answer 7

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

Answer 8

10.3

Answer 9

no 31.3

Answer 10

Yes you are correct

Answer 11

Remember
sin=SOH
cos=CAH
tan=TOA

Answer 12

O=opposite side
A=adjacent side
H=hypotenuse
