Answer:
x = 21.4
Step-by-step explanation:
We need to use the law of sins
sin 42 sin x
--------- = ----------
22 12
12 sin 42 = 22 sin x
12 sin 42 /22 = sin x
Taking the inverse sin of each side
sin^-1(12/22 sin 42) = sin^-1(sin x)
21.40637223 =x
To the nearest tenth
x = 21.4
Answer: x=−2
Step-by-step explanation:
x^3+2x^2+3x+6=0
(x+2)(x^2+3)=0
x+2=0 or x^2+3=0
x=−2
