Answer:
Step-by-step explanation:
SOHCAHTOA
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
(a is the adjacent side to the angle given) (o is the opposite side to the angle given) (h is the hypotenuse)
1) [tex]sin12=\frac{4.6}{h}, h=\frac{4.6}{sin12}[/tex] ; [tex]tan12=\frac{4.6}{a}, a=\frac{4.6}{cos12}[/tex]
2) [tex]cos58=\frac{18}{h}, h=\frac{18}{cos58}[/tex] ; [tex]tan58=\frac{o}{18}, o=18*tan58[/tex]
3) [tex]sin24=\frac{o}{8.5}, o=8.5*sin24[/tex] ; [tex]cos24=\frac{a}{8.5}, a=8.5*cos24[/tex]
4) [tex]sin 66=\frac{12}{h}, h=\frac{12}{sin66}[/tex] ; [tex]tan66=\frac{12}{a}, a=\frac{12}{tan66}[/tex]
5) [tex]sin38=\frac{5.9}{h}, h=\frac{5.9}{sin38}[/tex] ; [tex]tan38=\frac{5.9}{a}, a=\frac{5.9}{tan38}[/tex]
6) [tex]sin74=\frac{o}{10.4}, o=10.4*sin74[/tex] ; [tex]cos74=\frac{a}{10.4}, a=10.4*cos74[/tex]
hope this helps, still didn't get it. The final answers can be found by typing the expressions into a calculator.
