You are sailing your boat in the Chesapeake Bay to Thomas Point Lighthouse. You see a weather buoy, and you

Oh...no…I’m in big trouble. In all the days, why today do we have to have a pop quiz in math? I didn’t EVEN study! I just hate math! Ever since I started algebra, math has gotten harder and harder! Every time I look at an equation, the numbers get all mixed up and jumbled in my brain, and I try to remember the way to solve the problem. And by the time I find out how to solve that problem, HALF of the class is already DONE! But today might be a different day. Like they say, if you believe in yourself, anything is possible. Oh,no, Mr. Boyd is coming! (The teacher places the quiz in front of her/him.) (She/he looks at the quiz.) Oh, this doesn’t look half as bad. Ok, if two x plus fifty equals four x plus nine, then you bring the two over and… oh no! I forgot what you do next! (Sighs) ok, focus, focus. Breathe in, and breathe out.(Sighs) Ok, I got this.(Completes the rest of the quiz without a problem.) Finished! (Teacher comes by to collect his/her work.) Ok, I think I did good. I swear for the REST of my life I will never do a math problem again!

Hope you like it. I have hard time with Algebra.

Answer:

x is approximately 69.39 degrees.

Step-by-step explanation:

To find x in this triangle, we can use the sin rule:

$\frac{a}{sin(A)} =\frac{b}{sin(B)}$

The corresponding angle for each length is the one that lies directly opposite it. E.g. if 3.5 was our length 'a', then 55 degrees would be our angle A.

So let's take 3.5 and 55degrees as our length and Angle A, and 4 and x degrees as our length and angle B as we are trying to solve for x.

This would give us the following equation:

$\frac{3.5}{sin(55)} =\frac{4}{sin(x)} \\$

Since we are solving for an angle, it will be easier to rearrange the equation if we have it as the numerator, so we can flip the fractions to make it easier. It will still be equal as we are looking for the ratio.

$\frac{sin(55)}{3.5} =\frac{sin(x)}{4} \\$

From here let's isolate the sin(x) by multiplying by 4 and solving the values we have so far:

$\frac{4 sin(55)}{3.5} =sin(x)\\\frac{3.2766}{3.5} =sin(x)\\0.936=sin(x)$

Now the final step is to use inverse sin to cancel the sin so we just have x:

$sin^{-1} 0.936=x\\x=69.39$

x is approximately 69.39 degrees.

Hope this helped!
