Answer:
Angles 1 and 3 are congruent as vertical angles; angles 3 and 7 are congruent as corresponding angles.
Step-by-step explanation:
<1 and <3 are vertical angles because they are formed by the same lines and are opposite each other . 3 and 7 are corresponding angles because they are in the same position at each intersection where a straight line crosses two others. Since the lines are parallel, they are equal That makes 1 and 7 equal
Step-by-step explanation:
V=(4/3) * πr^3
V=(4/3) * π * 7.6 ^3
V=(4/3) * π * 438.976
V= π * 585.301333
V = 1837.85 inch^3
3.14 for pi btw
Answer:
a = 6, b = 22.5
Step-by-step explanation:
One triangle is 2.5 times bigger than the other.
9*2.5=22.5 which means b = 22.5
15/2.5=6 which means a = 6
Answer:

Step-by-step explanation:
Parallel lines have the same slope
The slope of the line shown is 
Therefore, the slope of the parallel line will also be
