Answer:

5.5

Step-by-step explanation:

We use right triangle XVW.

For <W, VX is the opposite leg.

WX is the hypotenuse.

The trig ratio that relates the opposite leg to the hypotenuse is the sine.

$\sin W = \dfrac{opp}{hyp}$

$\sin W = \dfrac{VX}{WX}$

$\sin 43^\circ = \dfrac{VX}{8~mi}$

$VX = 8~mi \times \sin 43^\circ$

$VX = 5.5~mi$

Find the measure of DC if m

kupik [55]

Answer:

B. 132°

Step-by-step explanation:

Find the measure of arc BD

m∠A = 1/2(arc BC - arc BD)
2*36° = 150° - arc BD
arc BD = 150° - 72° = 78°

Find the measure of arc DC

arc BD + arc BC + arc DC = 360°

arc DC = 360° - (150° + 78°) = 360° - 228° = 132°

Correct choice is B

Tom [10]

Answer:

3¼

Step-by-step explanation:

$formula \frac{{y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} }$

We take any of the two points shown in the question. I will take (-3, 1) and (1, 14).

x¹ = -3

y¹ = 1

x² = 1

y² = 14

Now, we sub these figures into the formula.

$\frac{14 - 1}{1 - ( - 3)}$

This leaves us with 14-1/1+3, which we can make into 13/4

13/4 = 3¼

Disclaimer: It is not actually x (or y) in the power of two, but a way to distinguish one x (or y) from the other. It is a label of sorts.

6x+2y= 6x+2y= \,\,16 16 2x-2y= 2x−2y= \,\,32 32

Ivanshal [37]

Answer:

x = 6, y = -8

Step-by-step explanation:

First we take the equations side by side and put them like this:

6x + 2y = 16

+ 2x - 2y = 32

8x = 48

Then solve for x.

x = 6

Then insert x back into either equation

2(5) - 2y = 32

10 - 2y = 32

solve for y,

y = -10
