Please HELP!!!!

Answer 1

Answer: 184.08 l.y.

Step-by-step explanation:

Let the width of Orion's belt is x light year.

By cosine law,

$(x)^2 = (915)^2+(736)^2-2\times 915\times 736 cos3^{\circ}$

$(x)^2 = 837225+541696-1346880 cos3^{\circ}$

$(x)^2 = 837225+541696-1345034.14777$

$(x)^2 = 33886.8522298$

$x = 184.08381849\approx 184.08$

Thus, the width of the Orion's belt is 184.08 light year.
