We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.
Angle x isn't the same as the 40° angle so it must be its supplement.
Answer: C 140°

r=1.2, h=2.9, V = (1/3) πr²h
Nothing hard here, we just plug in the numbers,
V = (1/3) π (1.2)² (2.9) ≈ 4.37310
Answer: B. 4.4 cubic inches
4.
Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is
Answer: B similar not congruent
5.
The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°
Answer: A 70°
Answer:
We would need pictures of the figures first :(
The order of locations from highest to lowest is Caspian sea, lammefjord, Trins Alexanderpolder, Fenland, Raczki
Explanation:
The order of the locations from highest to lowest can be determined using the values of meters below sea level.
From the data, the highest to lowest value can be written as
28 meters
8 meters
7 meters
4 meters
2 meters
Thus, from the data, the locations from highest to lowest can be written as
Caspian sea
Lammefjord
Trins Alexanderpolder
Fenland
Raczki
Answer:
1: -3
2: She gives him $3 per week
3: 18
4: How much money she initially borrowed
5: y = -3x + 18
