Question

100 POINTS AND BRAINLIST

Answer 1

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 2

Answer:

• Explained and Given Below.

Trigonometry rules:

• $\sf sin(x)= \dfrac{opposite}{hypotensue}$

• $\sf cos(x)= \dfrac{adjacent}{hypotensue}$

• $\sf tan(x)= \dfrac{opposite}{adjacent}$

using the formula's:

$\sf sin(x) = \dfrac{a}{c}$

$\sf cos(x) = \dfrac{b}{c}$

$\sf tan(x) = \dfrac{a}{b}$
