well, 30 would be 900
and 28 would be 784
so do my proportion thing again
28 x 30
784 872 900
(872 -784)/ (x-28) = (900-784)/(30-28)
x-28 = 2*88/116
x = 28 + about 1.5
or around 29.5
so
30
try calculator
sqrt (872) = 29.529
and 28 would be 784
so do my proportion thing again
28 x 30
784 872 900
(872 -784)/ (x-28) = (900-784)/(30-28)
x-28 = 2*88/116
x = 28 + about 1.5
or around 29.5
so
30
try calculator
sqrt (872) = 29.529
