Answer:
x° = arcsin(15.5/26.9×sin(73°))
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side:
sin(x°)/15.5 = sin(73°)/26.9
sin(x°) = (15.5/26.9)sin(73°) . . . . . multiply by 15.5
Using the inverse function, we can find x.
x° = arcsin((15.5/26.9)sin(73°))
