Find the slope of the line through the pair of points (2,-4), (-17,6)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

answer: x=60

its totaly b
