Me. 10 points i need with numbers 2, 3, 5, 7, and 8

I did two of these then lost my tab.  That's annoying.

Why'd you post 6 on its own page if you don't need it done?

Anyway,

2. Alternate angles from parallel lines are congruent so

62 = 4x + 2

60 = 4x

x = 60/4 = 15

and

12y = 144

y = 144/12 = 12

x=15, y=12, first one

3. Alternate angles are congruent; these are interior which I think means between the lines.

alternate interior, last choice

5.

They should have included the units of degrees on the 36.  

Those are supplementary angles (add to 180 degrees) when f and g are parallel so

3x + 5x+ 36 = 180

8x = 180 - 36 = 144

x = 144/8 = 18

18  second choice

7.

Let's call them A, B=31, C=72 instead of 1 2 3.

The third angle of the triangle is supplementary to angle A, because they're formed by the intersection of two lines.  

The triangle angles add to 180, so we get

(180 - A) + B + C = 180

or

A = B + C

So A = 31 + 72 = 103

103, last choice

8.

1 and 8 are both exterior to the two apparent parallel lines, which means they're not angles in between the lines (I think).  nope

1 and 7 also both exterior, nope

2 and 7, both exterior, nope

3 and 6,  yes, those are alternate interior angles to parallel lines, so are congruent.  The interior doesn't matter so much; alternate angles to parallel lines are congruent.

3 & 6, last choice

-6 is the correct option from the above given options
