Question

CAN SOMEONE HELP ME I ASKED TWICE PLEASE!!!

Answer 1

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) $sin12=\frac{4.6}{h}, h=\frac{4.6}{sin12}$ ; $tan12=\frac{4.6}{a}, a=\frac{4.6}{cos12}$

2) $cos58=\frac{18}{h}, h=\frac{18}{cos58}$ ; $tan58=\frac{o}{18}, o=18*tan58$

3) $sin24=\frac{o}{8.5}, o=8.5*sin24$ ; $cos24=\frac{a}{8.5}, a=8.5*cos24$

4) $sin 66=\frac{12}{h}, h=\frac{12}{sin66}$ ; $tan66=\frac{12}{a}, a=\frac{12}{tan66}$

5) $sin38=\frac{5.9}{h}, h=\frac{5.9}{sin38}$ ; $tan38=\frac{5.9}{a}, a=\frac{5.9}{tan38}$

6) $sin74=\frac{o}{10.4}, o=10.4*sin74$ ; $cos74=\frac{a}{10.4}, a=10.4*cos74$

hope this helps, still didn't get it. The final answers can be found by typing the expressions into a calculator.
