180=45x and x is 4 4x45=180
Less likely as there are only 3 numbers with a multiple 3 6 and 9 but there are more numbers which are not 1 2 4 5 7 8 10
Answer:
X=8 degrees
Step-by-step explanation:
We know that the straight line is 180 degrees and (13x+1)+(7x+19) is equal to 180 degrees (the line) so just solve :)
Hope this helps! attachment for work.
|r+3| = (r+3) when r ≥ -3 so for r ≥ -3
r + 3 ≥ 7
r ≥ 4
|r+3| = -(r+3) when r < -3 so for r < -3
-(r + 3) ≥ 7
r + 3 ≤ -7
r ≤ -10
The answer to this question is r ≤ -10, r ≥ 4
