Question

In ΔRST, the measure of ∠T=90°, the measure of ∠R=67°, and TR = 94 feet. Find the length of RS to the nearest tenth of a foot......

Answer 1

Answer:

240.6 ft is your answer of your question.

Answer 2

Answer:

240.6 feet

Step-by-step explanation:

to understand this

you need to know about:

• trigonometry
• PEMDAS

let's solve:

to find x we will use cos function

$\quad \: \cos( \theta) = \dfrac{adj}{hypo}$

substitute the value of $\theta$ and adj:

$\quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x}$

cross multiplication:

$\quad \: x\cos(67^{\circ})= 94$

divide both sides by cos(67°) :

$\quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6$
