Answer:

x = 5 , y = 5 $\sqrt{3}$

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values.

sin30° = $\frac{1}{2}$ , cos30° = $\frac{\sqrt{3} }{2}$ , then

sin30°= $\frac{opposite}{hypotenuse}$ = $\frac{x}{10}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5

and

cos30° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{10}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2y = 10 $\sqrt{3}$ ( divide both sides by 2 )

y = 5 $\sqrt{3}$

Find the slope of the line containing the given pair of points. If the slope is undefined, state this. (-8,0) and (4,0)

ahrayia [7]

Answer:

The slope is 0

Step-by-step explanation:

Given

$(x_1,y_1) = (-8,0)$

$(x_2,y_2) = (4,0)$

Required

The slope (m)

This is calculated as"

$m=\frac{y_2-y_1}{x_2 - x_1}$

$m=\frac{0-0}{4 -(-8)}$

$m=0$

The slope is 0
