Someone help plz! And plz make sure it’s right !

16^2 = 8^2 + x^2

x^2 = 16^2  -8^2

x^2 = 256 -64

x^2 = 192

x = sq root (192) =  13.8564064606

Step-by-step explanation:

i don't know if this is right, if it is wrong i'm sorry, but basically it is 12.7m

The problem states that the law of sines needs to be used but the function tangent can also be used to solve this. Either way, the same answer will be obtained
Using the law of sines:
sin 28 / 1.6 = sin (180 - 28 - 90) / x
where x is the horizontal distance between the ends of the beams
Solving for x
x = 3.01 meters

The answer is
3.0 meters
