Gianna is making two different salads. One calls for 3 3/4 cups chopped spinach. The other calls for 2 2/3 cups chopped spinach.

<h2> The answer is very simple add the whole numbers then find the LCM of 3 and 4 which is 12 then multiply 3/4 by 3 which will be 9/12 then multiply 2/3 by 4 which will be 9/12 then we add 9/12 + 8/12 which will equal to 5 17/12 which we can reduce and answer will be 6 5/12 spinach.</h2>

If sin(x) = cos(y) for acute angles x and y, how are the angles related?

Vesnalui [34]

Answer:

b. complementary

Step-by-step explanation:

-Complementary angles are angles that add up to 90°.

-These are usually the two acute angles in the right triangle.

#To verify, lets take the two angles 30° and 60°:

$Cos \ 60\textdegree=0.5\\\\Sin \ 30\textdegree=0.5\\\\\therefore Sin \ 30\textdegree=Cos \ 60 \textdegree=0.5$

#We can reverse as:

$Sin \ 60\textdegree=0.86603\\\\Cos \ 30\textdegree=0.86603\\\\\therefore Sin \ 60\textdegree=Cos \ 30\textdegree=0.86603$

Hence, two angles are said to be complimentary if they sum up to 90°.
