What's two thirds of a straight line?
Komok [63]
Well if the straight line is equal to 1 then your answer is 2/3 but if the straight line is not equal to 1 you need to know what it is equal to or you could use the equation y = (2/3)x
"x" would be the length of the straight line and "y" would be two-thirds of it

Geometry help will give brainliest
blsea [12.9K]
In a parallogram the two angles on the same side ( Angle T and Angle C) equal 180 degrees

So we have 8x +29 + 2x +11 = 180

combine the like terms:
10x + 40 = 180

Subtract 40 from each side:
10x = 140

Divide each side by 10:
X = 140 /10
X = 14

Now we have X, replace X into the equation for angle C

2(14) +11 = 28 + 11 = 39 degrees
