Just set up an equation comparing the two ratios and solve for the length, in this case x.
(10/19)=(6/x)
19/10=x/6
114/10=x
Answer= 11.4 feet for the length of the flower
3(100-b) = 6b
300-3b = 6b
+3b +3b
300 = 9b
/9 /9
b=33.33333... or 33 1/3
Hope this helps!

It's true! Cause the angle is acute it's supplementary angle would be obtuse
