A triangle with interior angles measuring a, b, and c degrees and exterior angle measuring d degrees is shown above. If d measures 140°, what is the
sum of a and b?

That would 40 degrees.

(Sorry I can't explain rn) It would have to do with exterior angles.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

i believe that the slope of the line is -5
