Answer:
Since angle d, a, and e are supplementary, d+a+e =180 degrees.
Given that line LK and BC are parallel
By the alternate interior angle theorem, e=c and d=b.
Substitute:
d+a+e=b+a+c=180
Since b+a+c is the sum of the angles of triangle ABC, the sum of the interior angle of triangle ABC (which could be any triangle of any size and shape) is 180 degrees.
Answer:
y ≥ 3x -1; x +3y ≤ 6
Step-by-step explanation:
Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.
The line with a slope of +3 is shaded <u><em>above</em></u> the line, so that will correspond to the inequality ...
y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.
Answer:
60
Step-by-step explanation:
interior angles for a triangle is 180°
180 ÷ 3 sides = 60°
