Answer:
The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary, or add up to 180 degrees
Step-by-step explanation:
Okay so this is not too hard once you get the grasp of it. What you want to do is put everything with each other giving you the answer, -3x^2 +42x^2 -147x
Answer:
see explanation
Step-by-step explanation:
The main diagonal is the perpendicular bisector of the other diagonal. However the other diagonal does not bisect the main diagonal.
Thus the diagonals do not bisect each other.
Answer: 34
Step-by-step explanation:
Answer:
x = 1, y = 46
Step-by-step explanation:
Since the triangles are congruent then corresponding sides and angles are congruent, then
DE = AB , that is
3x + 6 = 9 ( subtract 6 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
and
∠ C = ∠ F
10x + y = 56 ( substitute x = 1 )
10(1) + y = 56
10 + y = 56 ( subtract 10 from both sides )
y = 46
