Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm
Answer:
lesser x = -4
greater x = 1
Step-by-step explanation:
here's the solution :-
=》
=》
=》
=》
now, there are two cases
case 1) where x + 4 = 0
=》x = -4
case 2) where x - 1 = 0
=》x = 1
