Answer:
I got 28
Step-by-step explanation:
I use the slope formula
Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.
Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).
Because the two red angles within B are congruent, divide your angle measure in half.
From there, do the law of sines to solve for x. Good luck!

Answer:
Step-by-step explanation:
1. You kwnow that x and y vary directly, therefore, the expression has the following form:
Where is the constant of variation.
2. You have that and , so, if you substitute these values and then you solve for the constant of variation, you obtain the following result:
3. The answer is the first option.
That’s the answer for 3(3c-d)
