Answer:
25. x=19
26. 16=x
27 28=x
28. 24=x
Step-by-step explanation:
25. The two angles make a straight line (180 degrees)
6x-17 + 3x+26 = 180
Combine like terms
9x +9 = 180
Subtract 9 from each side
9x+9-9=180-9
9x = 171
Divide by 9
9x/9 = 171/9
x=19
26. These angles are corresponding angles and corresponding angles are equal if the lines are parallel
4x+20 = 6x-12
Subtract 4x from each side
4x-4x+20 = 6x-4x-12
20 =2x-12
Add 12 to each side
20+12 = 2x-12+12
32=2x
Divide by 2
32/2 = 2x/2
16=x
27 These are alternate interior angles and alternate interior angles are equal if the lines are parallel.
4x+30 = 6x-26
Subtract 4x from each side
4x-4x+30 = 6x-4x-26
30 = 2x-26
Add 26 to each side
30+26 =2x-26+26
56= 2x
Divide by 2
56/2 = 2x/2
28=x
28. These are corresponding angles and corresponding angles are equal if the lines are parallel.
99=3x+27
Subtract 27 from each side
99-27 = 3x+27-27
72 = 3x
Divide by 3
72/3 = 3x/3
24=x
Answer:
9
Step-by-step explanation:
Answer:
Because when you are finding slope the line must be linear and because it is linear it doesnt matter which point you get because you get the same answer (you can try it yourself)
