Sagot :
Answer:
Step-by-step explanation:
Again, by definition, for a right-angled triangle:
sinx = opposite side / hypothesis
= a / c
cosx = adjacent side / hypothesis
= b / c
tanx = opposite side / adjacent side
= a / b
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]
