The last one if I'm not mistaking
Answer: The correct answer is Choice D, 43 mm.
When you know 2 sides of a triangle, you can find the range for the final side of the triangle.
First, if we subtract 36 - 23 = 13, the third leg must be more than 13. Otherwise, the two smaller legs would not meet to make the third leg.
Second, if we add 36 + 23 = 59, the third leg must be less than 59. Otherwise, the third leg would reach further than the other two legs could reach.
43 is the only number larger than 13 but smaller than 59 in our list.
1 = 32
2 = 148
3 = 32
4 = 148
5 = 32
6 = 148
7 = 32
8 = 148
770 because the 1 is higher than 5 so you round up
