Answer:

Step-by-step explanation:

Again, by definition, for a right-angled triangle:

sinx =  opposite side / hypothesis

= a / c

Answer:

  • Explained and Given Below.

Trigonometry rules:

  • [tex]\sf sin(x)= \dfrac{opposite}{hypotensue}[/tex]
  • [tex]\sf cos(x)= \dfrac{adjacent}{hypotensue}[/tex]
  • [tex]\sf tan(x)= \dfrac{opposite}{adjacent}[/tex]

using the formula's:

[tex]\sf sin(x) = \dfrac{a}{c}[/tex]

[tex]\sf cos(x) = \dfrac{b}{c}[/tex]

[tex]\sf tan(x) = \dfrac{a}{b}[/tex]
