Answer 3

a right triangle

youre given \( \theta \) and adjacent

height (x) is the opposite leg of the triangle

so, what are we going to use?

SOH? CAH? TOA?

Answer 4

toa ?

Answer 5

yes
\[ \theta=49^\circ \]
\[ adjacent=900 \]
\[ opposite= x \]
TOA \( \Rightarrow \tan \theta= \frac{opposite (x)}{adjacent} \)

\[ \tan49^\circ = \frac{x}{900} \]
\[ \tan49^\circ \times 900 =x \]
