Answer:
-39
Step-by-step explanation:
just took the quick check
A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81

Answer:
x = -3
Step-by-step explanation:
the lines in the form:
y = a , where a is a constant is a horizontal line
and
x = b, where b is a constant is a vertical line
To find lines that are parallel to the horizontal and vertical lines with point given (n,p), we follow the rule below:
1. If we have a line y = a and goes through point (n,p), the parallel line will have equation y = p
2. If we have a line x = b and goes through the point (n,p), the parallel line will have equation x = n
<em><u>Now, this question gives a vertical line x = -11 and we need to find line parallel to this that goes through (-3,9). So, from RULE #2 above, we can say the parallel line's equation would be:</u></em>
x = -3
