Answer:

Since a triangle has 180 interior degrees, and 81+57=138, and 180-138=42, you need to find _*2+18=42. (Hint, you can subtract the 18 from the 42, and find _*2=24).

Find the distance between (5, 9) & (-7, -7). Round to the nearest tenth.

coldgirl [10]

Distance equals end minus start

(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)

(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20

So the distance between the two points is 20

Answer:

Step-by-step explanation:

$\frac{(-5)^{3} + 17}{10(2 - 6) - 2(5 + 2)}\\\\\frac{(-125) + 17}{10(-4)-2(7)}\\\\\frac{-108}{-40-14}\\\\\frac{-108}{-54}\\\\2$
