What is the length x of the side of the triangle below? (hint: use the cosine function.) a. 1.9 b. 2.4 c. 1.6 d. 2.1

Answer

The correct answer is A.

Explanation

The given triangle is a right triangle.

The length of the hypotenuse is units.

The given angle is .

The unknown side is adjacent to the given angle.

We can therefore use the cosine function to find .

Recall the mnemonics CAH.

This means that;

This implies that,

We multiply both sides by to get,

We evaluate to get

Therefore the length of the side of the triangle is units to the nearest tenth.

tube or goog with be a great resource to with that question

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
