You will add 2 to both sides and subtract 3x on both sides to get x on one side and a whole number on one side. So after doing that, you should get 12 = 4x and x will equal to 3

Find the value of x.
pychu [463]

Knowing that all triangles angles add up to 180*:

24* + x + ? = 180*

Knowing the straight line is 180*:

180* - 122* = 58*

The equation then is:

24* + x + 58* = 180*

Then solve for X:

(82* + x) - 82* = (180*) - 82*

<u>x = 98* or C</u>

If costheta=4/5 then what is sec^2theta
DaniilM [7]

Answer:

\sec^2(\theta)=\frac{25}{16}

Step-by-step explanation:

Recall what the relationship between cosine and secant:

\sec(\theta)=\frac{1}{\cos(\theta)}

In other words, secant is the reciprocal of cosine.

So, if we know cosine, we only need to find its reciprocal to find secant.

We are given that cosine is:

\cos(\theta)=\frac{4}{5}

Then secant must be:

\sec(\theta)=\frac{5}{4}

So:

\sec^2(\theta)=(\frac{5}{4})^2

Square:

\sec^2(\theta)=\frac{25}{16}

And we're done!

The equation for a line in slope-intercept form is:

y=mx + b

m: slope

b: y-intercept

x,y: x and y coordinate pair

So the answer would be...

y=-4x-10
