Hey there! I'm happy to help!

To find this other side given an angle and a side, we will use a trigonometric function. The three basic ones are sine, cosine, and tangent. You can remember these and what what they are using the mnemonic "soh cah toa".

SOH: Sine= Opposite/Hypotenuse

CAH: Cosine= Adjacent/Hypotenuse

TOA: Tangent= Opposite/Adjacent

We see that the sides involved are the opposite and hypotenuse.

Therefore, we can write this equation.

sin40= w/28

We multiply both sides by 28 to isolate the w.

28×sin40=w

Now, we find the sine of 40 on our calculator and then we multiply it by 28.

w≈18

Therefore, the answer is 18 cm.

I hope that this helps! Have a wonderful day!

<h3>Explanation:</h3>

Part 1

We can list our facts first:

Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

$6.5 \times 1.5 = 9.75 \: teaspoons$

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

$9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp$

Image result for How to find volume of sphere explain step by step

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.

response error.

Step-by-step explanation:

A response error shows the lack of accuracy in the customer responses to the survey questions. A response error can be caused by a questionnaire that requires framing improvements, misinterpretation of questions by interviewers or respondents, and errors in respondents' statements. Some responses are influenced by the answers provided to previous questions, which introduces response bias.
