1936 --> 1936.000
However; I believe your question is wrong.
You would have use the equation:
X1-Y2/Y2-X1= 0-5/ 5-0=-5/5 and your will be -1
I believe it is an acute triangle
but I also am confused on this one
The average weight is 114 pounds of all 5 children.
3 * 120 = 360
2 * 105 = 210
210 + 360 = 570
570 / 5 = 114
