their are no angles. sorry cant .
step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
use a calculator to find that 845/73 = 11.575
the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.
subtract that result from 845 to get 845 - 803 = 42
the equivalent expression are always the hardest ones but you look at the gcf also
