<u>Trigonometric Ratios
</u>
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the right triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The image provided shows a right triangle whose hypotenuse is given. We are required to find the value of both legs.
Let's pick the angle of 30°. Its adjacent side is y. We can use the cosine ration, which is defined as follows:


Solving for y:

Since:


Simplifying:

Now we use the sine ratio:


Solving for x:

Since:


Simplifying:

The choices are not clear, but it seems like the correct answer is C.


Answer:
28:12
Step-by-step explanation:
You multiply both sides by the same number to increase a ratio, the only one you can do this with is 28:12 by multiplying the original ratio by 4
Answer:
1/4 cup of oil for every 1 cup of water
Step-by-step explanation:
Lets take a look at the information given in the question
The recipe requires 1/8 cup of oil for every 1/2 cup of water.
We know that 1/2 + 1/2 is 1/1, or just 1 simplified
So if we are doubling the amount of water in the recipe, we have to do the same to the oil.
1/8 + 1/8 = 2/8, or 1/4 simplified
So the answer is 1/4 cup of oil to every 1 cup of water
