Consider a triangle abc like the one below. suppose that a = 27°, c = 78°, and b = 66. (the figure is not drawn to scale.) solve
the triangle.
round your answers to the nearest tenth.
if there is more than one solution, use the button labeled "or".

We don't get to see the figure but we don't need it.

The remaining angle B is

B = 180 - 27 - 78 = 75°

The Law of Sines gives the remaining sides

B=75°, a=31.0, c=66.8

No need for "or" on this one.  That happens when we know the sine of an angle so there are two possibilities for the angle, an acute one and an obtuse one that's supplementary.

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
