Answer:
Step-by-step explanation:
Since they're equidistant (equal distances), we can set them equal to one another and solve for x:
Adding 5 to both sides:
Subtracting 2x from both sides:
Dividing both sides by 3:
Therefore:
If you look in a table of sines, you find that sin(θ) = 0.45 corresponds to an angle of about 26°45', so is nearest to 27°.
