Their angles/lengths (depending on which type of graph you are using) would be the same.
1:2:3...total is 6
1/6 of 5 1/4 = 1/6 * 21/4 = 21/24 = 7/8
2/6 of 5 1/4 = 2/6 * 21/4 = 42/24 = 1 3/4
3/6 of 5 1/4 = 3/6 * 21/4 = 63/24 = 2 5/8
7/8, 1 3/4, 2 5/8...total = 5 1/4 inches
13) B. 8.47,8.67,8.7
14) A
Just ask for explanation if u need it
Hope that helped :)
