compare the 5 and 10 dimension then the 7 and 14 dimensions
10/5 =2
14/7 =2
they both are the same ratio/factor
the factor is 2
ST is not he midpoint of SN because y=15 and if you plug in you get SN to be 150 but ST is only 64 which is not half of 150
29 degrees. You can just add 12 and 17 to find this, since the 12 is negative
14x - 129 (I think I’m so sorry if it’s wrong)
