Answer: 8.2

Step-by-step explanation:

As angles in a triangle add to 180 degrees,

$\angle A=180^{\circ}-121^{\circ}-31^{\circ}=28^{\circ}$

So, by the Law of Sines,

$\frac{a}{\sin A}=\frac{b}{\sin B}\\\\a=\frac{b \sin A}{\sin B}\\\\a=\frac{9 \sin 28^{\circ}}{\sin 31^{\circ}}\\\\a \approx \boxed{8.2}$

50 pts!!! Given: x - 6 1/3 ≤ 1 1/2. Choose the solution set.

maw [93]

Answer:

{x | x R, x ≤ 7 5/6 }

Step-by-step explanation:

we have

$x-6\frac{1}{3} \leq 1\frac{1}{2}$

Convert mixed number to an improper fraction first

$6\frac{1}{3}=\frac{6*3+1}{3}=\frac{19}{3}$

$1\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$x-\frac{19}{3} \leq \frac{3}{2}$

Multiply by 6 both sides to remove the fractions

$6x-38 \leq 9$

Adds 38 both sides

$6x \leq 9+38$

$6x \leq 47$

Divide by 6 both sides

$x\leq \frac{47}{6}$

convert to mixed number

$\frac{47}{6}=\frac{42}{6}+\frac{5}{6}=7\frac{5}{6}$

substitute

$x\leq 7\frac{5}{6}$

therefore

{x | x R, x ≤ 7 5/6 }
