Step-by-step explanation:
when 2 lines cross, the angles on one side of one of these lines are mirrored to the other side.
and crossing a second, parallel line creates exactly the same angles there too, because crossing the second line is like crossing the first line. otherwise the 2 lines are not parallel. the second line is just a shifted version of the first line (and vice versa). all the other attributes are the same.
and all angles around a single point on one side of a line are together 180°.
because of all that,
angle 2 = angle 3 = angle 6 = angle 7 = 76°
angle 1 = angle 4 = angle 5 = angle 8 = 180-76 = 104°
Answer:
3 pieces that are 1/2 units long,
6 pieces that are 1/4 units long,
or 12 pieces that are 1/8 units long.
Step-by-step explanation:
Multiplying these fractions respectively makes a fraction that is 1 ½ units long

Answer:
120
Step-by-step explanation:
-3y(-5y+10)
=15y^2-30y
y=4
15(4)^2-30(4)
=240-120
=120
