The answer is <span>12^2=x^2+8^2-16x(cos(72°) </span>
<span>x^2-4.9443x=80 </span>
<span>(x-2.4721)^2=86.1115 </span>
<span>x-2.4721=±9.2796 </span>
<span>x=11.7517 </span>
<span>B=72°, b=12, c=8, a=11.8 </span>
<span>C=arcsin(8/12*sin(72°))=39.3° </span>
<span>A=68.7° </span>
Θ = 290°
to convert to radians it should be multiplied by π/180
∴ θ = 290 * π/180 ≈ 5.0615 rad.

Answer:
x =12
Step-by-step explanation:
1/2x + 3 = 2/3x + 1
1/2 = 3/6 ; 2/3 = 4/6
3 - 1 = 4/6x - 3/6x
2 = 1/6x
x = 12
