If an angle measures x degrees, its supplement measures (180-x) degrees.
This means that:
![x+178.2=180-x\\2x=180-178.2=1.8\\x=0.9](https://tex.z-dn.net/?f=x%2B178.2%3D180-x%5C%5C2x%3D180-178.2%3D1.8%5C%5Cx%3D0.9)
So, the angles measure ![\boxed{0.9^{\circ}, 179.1^{\circ}}](https://tex.z-dn.net/?f=%5Cboxed%7B0.9%5E%7B%5Ccirc%7D%2C%20179.1%5E%7B%5Ccirc%7D%7D)
It really depends on what it is for. i would say reasoning for school work. bc it is better to go with facts.
Hello :
the line has a equation : y = ax (<span>a y intercept at (0,0))
the slope is : - 1/3 ( product the slope = -1 ..... a×3 = -1)
the equation is : y = (-1/3)x

I think its 2 fifths i could be wrong cause i havent worked with fractions since 5th grade and im in 11th grade
Answer: it's 80 because h = -16t2 + 64 = 80
