Answer:

D. 21/29

Step-by-step explanation:

Formulas used:

sin θ = sin (180 - θ)
sin θ = opposite/hypotenuse

Opposite:

y- coordinate of given point = 21

Hypotenuse:

√x²+y² = √20²+21²= √841 = 29

Then

sin θ = 21/29

The inequality 6 - 2/3x < x - 9 is equivalent to...

Dafna11 [192]

Start with

$6-\dfrac{2}{3}x$

Add 9 to both sides

$15-\dfrac{2}{3}x$

Add $\frac{2}{3}x$ to both sides

$15$

Multiply both sides by 3/5

$9$

Which is the same as

$x>9$
