Write an equation of the line that goes through the point (-5,-6) and is perpendicular to the line y= -1/2x + 1

1 answer:

3 0

So the (-5,-6) is negative so if you had the q1 q2 q4 q3 box both number will go down then left because it’s negative if it’s positive it’ll go up and then right

Please simplify the following trigonometric identity.

<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!

WHAT IS THE RELATIONSHIP BETWEEN THE ANGLE OF ELEVATION AND THE ANGLE OF DEPRESSION? GIVE AN EXAMPLE OF AN APPLICATION USING THE

Makovka662 [10]

Angles of Elevation and Depression are used in measuring heights and distances in trigonometric applications using right triangles. These angles are made when we look up or down to view objects. Devices are available to measure angles of elevation and depression. These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles
