To find the answer, you need to determine what the difference is. In this case, the difference is 6.
134 - 128 = 6
140 - 134 = 6
146 - 140 = 6
152 - 146 = 6
So, to find the answer you would add 6 to the next set of numbers to continue the pattern. For example -
152 + 6 = 158
158 + 6 = 164
All 3 triangle angles always add up to 180 degrees.
Angle to the left of 140 degrees = 40 degrees
Angle x = 180 -110 -40
Angle x = 30 degrees
Answer:
18
Step-by-step explanation:
2x - 8 = x + 10
- x - x
