Question

100-20
(x - 40° and (x + 10º are the measures of complementary angles. Find the measure of
each angle.​

Answer 1

Answer:

Here are 4 distinct expressions:

K = (6 / 2)(3);

L = 6 / 2(3);

M = 6 / 2 × 3;

N = 6 / (2 × 3).

The question is asking about L (after simplifying inside the parentheses 1 + 2 as 3, which all mathematicians agree should be done first), but many respondents are equivalent; however, there is far from universal agreement with this assumption. There is universal agreement (at least among cognizant people) that K is 9 and N is 1, but not on how to handle L and M.

Some terminology: a · b and a × b each
