A theater production group is making frames to support wall-like props. Three-foot beams form right triangles with 10-foot beams

to allow them to stand, as shown in the image.


What is x, the angle at which the diagonal beam meets the 10-foot beam at the top of the frame?

16.7°

17.5°

72.5°

73.3°

The main lesson students and teachers should take away from this problem is the correct answer should be: who cares?  The group built their frames with a ruler and a saw, got an exact slope of 10/3 and the angle measures didn't matter one bit.  The best angles measures are the ones avoided.

But trig as taught is all about angles. Gotta find the angle. Here we have a right triangle and we're interested in the angle at the top of the frame, opposite side 3, adjacent side 10, so

\tan \theta = \dfrac{3}{10}

\theta = \arctan \dfrac{3}{10} \approx 16.7^\circ

Please help it's the SLOPE
Maksim231197 [3]

Answer:

-  \frac{4}{5}

Step-by-step explanation:

Please see the attached picture.

slope \\  =  \frac{1 - ( - 3)}{ - 3 - 2}  \\  =  \frac{1 + 3}{ - 5}  \\  =  -  \frac{4}{5}

Solve the system by substitution
Lina20 [59]

Answer:

(-5, -30)

Step-by-step explanation:

We start with the equation:

y = 6x

y = -4x - 50

Since both of them are equal to y, we can substitute the 6x into y. So:

6x = -4x - 50

Now we can solve for x. Add 4x to both sides...

6x = -4x - 50

+4x   +4x

10x = -50

Now, divide both sides by 10.

<u>10x</u> = <u>-50</u>

10      10

x = -5

So, we now know that x is -5. Now we know this, we can substitute -5 where we see x. It works in both equations, so I will do both.

y = 6(-5)

y = -30

And...

y = -4(-5) - 50

y = 20 - 50

y = -30

As you can see, both equations show that y = -30. To check our work, let's plug in the values.

-30 = 6(-5)

-30 = -30

Also:

-30 = -4(-5) - 50

-30 = -20 - 50

-30 = -30

So, we can see that both of the equations gave us the same answer. So, our answer is x = -5 and y = -30, so the ordered pair is: (-5, -30). Hope this helps you!
