1.) m∠LAB = 40°  2.) m∠3= 123°  3.) x=25  4.) y = 29

5.) p is (-4, -3) 6.) B is (3,8)

Step-by-step explanation:

1.)  80/2 =40

2.) 180 -57 = 123

3.) 2x + 10 + 4x +2 =180  Combine like terms, solve for x = 150/6 =25

4.)  5y -25 +2y +2 =180   7y -23 =180   y= 203/7  y= 29

5.) Parallel lines divide a hypotenuse in proportion to the proportions on the legs  -6 -(-2) =8 8/4 = 2 Add 4 to -6 on horizontal. x= -2

6- (-6) =12  12/4= 3   Add 3 to -6 on the vertical  y = -3

6.)   Same assumption as 5  but add the differences to extend the line.

Horizontal: -5-(-1) =4  -1 + 4 = 3 is x   Vertical 6-4=2    2+6=8  y is 8
