Answer:

AB ≈ 5.6 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos62° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{BC}$ = $\frac{AB}{12}$ ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

Answer:

x > -1

Step-by-step explanation:

Divide the whole inequality by 9.

( $\frac{x}{3}$ +1)> $\frac{6}{9}$

$\frac{x}{3}$ > $\frac{2}{3}$ - 1

$\frac{x}{3}$ > - $\frac{1}{3}$

Multiply by 3.
