103+53=156
180-156=24
The third angle is 24
So then take 180 because a line is 180 degrees and subtract 24
156 is the final answer
The slope is 4/3 because rise over run (if u have heard of that expression)

Hi there!
9 + 1/2 (7n - 26) - 8n
= 9 + 7n*1/2 - 26*1/2 - 8n
= 9 + 3.5n - 13 - 8n
= 9 - 13 + 3.5n - 8n
= -4 + 11.5n
Hope this helps!
