Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
$495.28 I think I'm not sure if I'm right.
the two points are,
(5,4) & (7,10)
so the slope is,

so, the slope of the line is,
m = 3
The answer is 114, because they are alternate interior angles, so they are equal
Answer:
1.6
2. Honestly, I think it is, because it repeats at regular intervals. The period is -2.
