Answer:
Step-by-step explanation:
An indirect proof proves a statement by showing that the negation of the statement cannot be true. It can be a powerful tool when working with statements with "not" in them or inequalities.
The answer to your question is:
1) x = 11
2) x = 21
1)
3x + 2 = 35
3x = 35 - 2
3x = 33
x = 33/3
x = 11
2.-
2x = 42
x = 42 / 2
x = 21
40. x = 106 degrees
41. x = 118 degrees
40.
straight line has 180 degrees
180 - 128 = 52 : angle inside triangle
180 - 126 = 54 : angle inside triangle
52 + 54 = 106
triangle has 180 degrees
180 - 106 = 74 : 3rd angle inside the triangle
again straight line has 180 degrees
180 - 74 = 106 = x
41.
shape of 4 sides is 360 degrees
180 - 34 = 146
little box means one the sides is 90 degrees on either side
146 + 90 = 236
360 - 236 = 124
both x's are the same so angles inside are the same too
124 ÷ 2 = 62
straight line is 180
180 - 62 = 118
x = 118
1) 12, 24, 36, 48, 60, 72
2) 18, 36, 54, 72, 90, 108
3) 40, 80, 120, 160, 200, 240
4) 16, 32, 48, 64, 80, 96
5) 100, 200, 300, 400, 500, 600
6) 25, 50, 75, 100, 125, 150
7) 50, 100, 150, 200, 250, 300
8) 63, 126, 189, 252, 315, 378
