Answer:
Step-by-step explanation:
x = y/7
y-x = 18
y - y/7 = 18
(6/7)y = 18
y = 21
x = y/7 = 3
Answer:
A
Step-by-step explanation:
(2b-3)^2 = (2b-3)(2b-3) = 4b^2-12b+9
Answer:
me I don't no ooh
but I tink u should use ur text book
Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note:
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)
