Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:

$\frac{7}{21} =\frac{x}{18}$ and cross multiply to get

21x = 126 and

x = 6

Ciro rounds 280.05 to the nearest integer.

Alrighty, so 280.05 rounded to the nearest integer is 280. 280.05 rounded to tenths is 280.1. add those two together and you get 560.1.
