Answer:

Option D.) 100 \textdegree is correct.

Step-by-step explanation:

In a quadrilateral, ABCD, opposite angles are supplementary.

\angle BCD + \angle BAD  = 180\textdegree

therefore \angle BCD  = 180\textdegree - \angle BAD = 180\textdegree - 80\textdegree  = 100 \textdegree

therefore option D.) 100 \textdegree is correct.

Find the value of angel 0 to the nearest 10th<br>​
BaLLatris [955]

Answer: 36.9

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos or Tan.

To work out which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.

As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.

So first you would have to write:

Tanθ=3/4

Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.

θ=Tan-1 3/4

To find the answer you would have to put it in your calculator.

θ=36.9

Hope this helps :)

Pls help me with this question and explain how you got the answer!!!!!
Luba_88 [7]

Answer:

-87

Step-by-step explanation:

So, first to find <em>x</em> you need to subtract 121 from 180. You do this because both the angle which measures 121 degrees and <em>x</em> lie on the same line, and since a line has an angle measure of 180, you do 180-121 to find <em>x</em>. The same thing can be done for <em>y</em>. Since the angle measure of 34 degrees and y lie on the same line you can calculate 180-34 to get <em>y. </em>So, let's do that.

180-121=x

59=x

180-34=y

146=y

Once you've done that you can easily subtract the two and get your answer.

x-y

substitute the answer for the variables and get

59-146

and then your answer is

-87

A. g(x) = f(x)+5<br> B. g(x) = f(x+5)<br> C. g(x) = f(x)-5<br> D. g(x) = f(x-5)
bearhunter [10]

Answer:

<h2>         -3 and 2</h2>

Step-by-step explanation:

Te solutions of f(x) = g(x) are x-coordinates of points of intercept of the graphs.

Points of intercept are (-3, -8) and (2, -3)

So the solutions are:  -3  and  2
