Please simplify the following trigonometric identity.

lesya692 [45]

<u>Examining the question:</u>

We are given the expression:

$\frac{1}{Sec(\alpha)-Tan(\alpha)}$

We know from Basic trigonometry that:

$Sec(\alpha) = \frac{1}{Cos(\alpha)}$

$Tan(\alpha) = \frac{Sin(\alpha)}{Cos(\alpha)}$

<u>Simplifying the expression:</u>

Replacing these values in the given expression, we get:

$\frac{1}{\frac{1}{Cos(\alpha)} -\frac{Sin(\alpha)}{Cos(\alpha)} }$

Since the denominator of both the values in the denominator is the same:

$\frac{1}{\frac{1-Sin(\alpha)}{Cos(\alpha)} }$

We know that $\frac{1}{\frac{a}{b} }$ = $\frac{b}{a}$ , using the same property:

$\frac{Cos(\alpha)}{1-Sin(\alpha)}$

and we are done!

Gnom [1K]

Answer:

9 ft

Step-by-step explanation:

let x be the required distance.

$\frac{760}{x} =tan~ 89^\circ18 '\\x=\frac{760}{tan~89^\circ 18' } =\frac{760}{tan~89 \frac{18}{60}} =\frac{760}{tan~89.3^\circ} \\or~x \approx 9~ft$
