taki has her back to a wall. she starts to walk straight forward. she stops and turns 133° to the right and walks back in this d
Nikitich [7]
I'd like to assume that the triangle is a right triangle and you solve for x so...

133 + c = 180   (supplementary property to find one angle of triangle)
          c = 47

x = 180 - 90 - 47 (int. angles of triangle = 180)
   = 90 - 47
   = 43

Therefore, x is 43 degrees

The price of a television was reduced from 250 to 200. by what percentage was the price of the television reduced
Murljashka [212]

Answer:

20%

Step-by-step explanation:

We can start by finding out how much the price of the television was reduced by.

250 - 200 = 50

Now, we need to know what percent of 250 is 50? Let x represent the percent of 250 that is 50. Using this, we can set up an equation:

<u />x\%\times 250=50

Notice that a percentage can also be written as that number over 100.

\frac{x}{100}\times250=50

\frac{250x}{100}=50

Reduce the fraction (250 and 100 have a common factor of 10)

\frac{25x}{10}=50

Reduce the fraction again (25 and 10 have a common factor of 5)

\frac{5x}{2}=50

Multiply both sides by two

5x=100

Divide both sides by 5

x=20

Therefore the price of the television was reduced by 20%.
