3
Step-by-step explanation:
1+2+4+5+6+7+8+9+10+11+12+13 = 87
87/12 +7.25
these are corresponding angles

The additive inverse is the value that must be added to the number to give zero.
- 4 + 4 = 0
↑ additive inverse

count only the pair numbers between 200 and 240:
200, 202, 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226, 228, 230, 232, 234, 236, 238, 240
You <u>solve</u> the equation.
The process of finding variable values that make the equation true is called <em>solving</em> the equation.
