R+s-t-(r-s+t)

=2s-t is the answer



People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t

You would assume you would go r-r and thats 0 so no r's

you would say s-(-s) makes it plus and theres 2s

and you would say -t -(+t) is -t 

that's why the answer is 2s-t

At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t

Answer: x = 10

Step-by-step explanation:

The sum of all interior angles in a polygon add up to 360°

Meaning to find X we grab those numbers/variables and make them equal to 360°. This will give us an equation.

106 + 94 + 135 + x + ( x + 5 ) = 360

335 + x + x + 5 = 360

340 + 2x = 360

subtract 340 from both sides

2x = 20

Divide by 2

x = 10

Now solve the angle equations to find their angle.

( 10 + 5 ) = 15

x = 10

Now to check if it's right add them together

106 + 94 + 15 + 10 + 135 = 360 ( ITS CORRECT )

The question is below, plz answer, will give brainliest
Elina [12.6K]

By comparing the right triangle ABC with the triangle XYZ, we will see that:

  • AC = 5
  • BC = 10.

<h3>How to find the given segments?</h3>

So we know that the largest triangle is a dilation of scale factor 2 of the smaller one.

Also, remember that for right triangle we have the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Now, the problem tells us that:

tan(x) = 5/2.5

For the angle x, the adjacent cathetus is XY, and the opposite cathetus is YZ.

Then we have:

YZ  = 5

XY = 2.5

Knowing that the correspondent sides in the larger triangle will be 2 times the above ones, we can see that:

AC = 2*XY = 2*2.5 = 5

CB = 2*YZ = 2*5 = 10
