Answer:
yes it is a right triangle
Step-by-step explanation:
the angles meet up into a 90 degree angle causing it to form a right triangle.
OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

Answer:
x°=118
(x-56)°= 62
Step-by-step explanation:
90×2 = 180
360-180=180
x+(x-56) =180 x=118
118-56=62
Answer:
The correct answer is B) the mean will decrease and the median will stay the same.
Step-by-step explanation:
This is true because the mean is the average, which is all of the values added together and then divided by the number of teachers. Reducing anyone's salary will reduce the mean.
The median stays the same since she was already the lowest (or tied for the lowest) paid in the group. Therefore, the middle term (the median) is unchanged.
