To answer this problem, we can find to determine angle A first by taking the arc sin of 0.83. Angle A is equal to 33.9. Hence angle B should be 90-33.9 equal to 56.10. sin of 33.9 added to the sin of 56.10 is equal to 1.38. or we can just directly add the cos values since the sin is just the same as the complementary of each
The correct answer would be D !m
(x)+(x+1)+(x+2)=-36
3x+3=-36
3x=-39
x=-13
The numbers are -13, -12, -11
