Answer 1

1.)
<1 & <3 are vertically opposite angles
<3 & <8 are interior angles on the same side of the transversal
<4 & <14 are interior alternate angles
<6 & <12 are exterior alternate angles
<13 & <9 are corresponding angles
<4 & <7 are corresponding angles

<1, <3, <5, <7, <9, <11, <13, <15 = 95°
<2, <4, <6, <8, <10, <12, <14, <16 = 85°

Answer 2

2.) You can easily google brief responses.

Answer 3

And 3.)
Have you used the Distance Formula before @8bithelix?

Answer 4

no

Answer 5

The first step in solving 3.) Is finding the distance from point B to point C using the Distance Formula:
\[d = \sqrt{(x _{2}-x _{1})^2+ (y _{2}-y _{1})^2 }\]

Answer 6

B is at (4, -2)
C is at (-5, 1)
Plug them into the formula @8bithelix
