Answer:
6/sin 150 = 8 / sin B
Step-by-step explanation:
6/sin 150 = 8 / sin B
sin 150 = 1/2 so you cross multiply to get 6 sin B = (1/2) • 8
6 sin B = 4
sin B = 4/6
B = inverse sin (4/6) = 42º or 138º
But both of those add to 150 to go over 180 so there are no solutions.
Back in geometry, you had that the larger angle of a triangle is opposite the longer side, right? You can see that 150º can't be opposite 6 because then the angle opposite 8 would have to be larger than 150º which is impossible for a triangle.
They both are close 1/2 and you could cross multiply them
To find the amount of votes that the candidate that won received multiply 360 by .8.
360*.8 = 288
This means the winning candidate received 288 votes.
