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°.

the price of an antibiotic in one drugstore is $19.50 and $16.25 in another write the ratio of the prices
damaskus [11]
Remember that ratios are essentially fractions without fraction bars...

If they asked to find the ration of 19.50 to 16.25 you would set them up like so....

19.50 : 16.25      -----> since fractions can be simplified so can ratios in the same manner

the ratio you would end up with is <u>6 : 5</u><u />   

Ratios can be easily remembered and solved if you understand the link between them and fractions. 

I hope this helps! :D
