Answer:
11
Step-by-step explanation:
<em>When you subtract a negative number, you add them.</em>
<em>Example:  5 - (-5) = 5 + 5 = 10</em>
<em>Example:  1 - (-14) = 1 + 14 = 15</em>
<u>Step 1:  Subtract</u>
8 - (-3)
8 + 3

Answer:
   180, 180, 148, 180, 148
Step-by-step explanation:
The two rules in play here are ...
- the sum of interior angles of a triangle is 180°
- the angles of a linear pair are supplementary (they total 180°)
__
The first of these rules answers the first two questions:
- interior angles total 180°
- angles 1, 3, 4 total 180°
We can subtract the measure of angle 1 from both sides of the previous equation to find the sum of the remaining two angles.
- angles 3 and 4 total 148°
The second rule answers the next question:
- angles 1 and 2 total 180°
As before, subtracting the value of angle 1 from both sides of the equation gives ...
_____
<em>Additional comment</em>
Of course, the subtraction property of equality comes into play, also. For some unknown, X, you have (in both cases) ...
   X + 32° = 180°
   X +32° -32° = 180° -32° . . . . . . subtraction property of equality
   X = 148° . . . . . . . . simplify
In the first case, X is the sum of angles 3 and 4. In the second case, X is angle 2 only.
