If the one side of the smaller polygon is 2 and the same side of the larger polygon is 5, than there is a ratio of 2 1/2. Meaning, that since the area of the small polygon is 20, the area of the larger polygon must be 50.

Reason:

20 x 2 1/2

20 + 20 + 10 = 50

Answer:

C) 50

Let me know if I'm wrong. I did the math in my head, so I'm not 100% positive. Sorry if this doesn't help :(

Step-by-step explanation:

don't panic. just breathe and think logically.

why would these angles be different ? how could they be different ?

right : they cannot be different. otherwise the 2 horizontal lines would not be parallel.

so, yes, indeed, these 2 angles are identical.

3x + 2 = 2x + 6

x = 4

that's it.

If the endpoints of AB are at (-4, 5) and (2, -7), what is the length of AB?​
Sonbull [250]

Answer:

The length of AB is 6\sqrt{5} units

Step-by-step explanation:

The rule of the distance between two points (x1, y1) and (x2, y2) is

  • d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}

∵ The endpoints of AB are (-4, 5) and (2, -7)

→ Let point (-4, 5) be (x1, y1) and point (2, -7) be (x2, y2)

∴ x1 = -4 and y1 = 5

∴ x2 = 2 and y2 = -7

→ Substitute them in the rule above to find the length of AB

∵ AB=\sqrt{(2--4)^{2}+(-7-5)^{2} }=\sqrt{(2+4)^{2}+(-12)^{2}}

∴ AB=\sqrt{(6)^{2}+144}=\sqrt{36+144}

∴ AB=\sqrt{180}=6\sqrt{5}

∴ The length of AB is 6\sqrt{5} units
