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

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

answer: #1 ads up by 8 and i don't know #2
