<h2>Answer:</h2>

<u> Angle C is 7 * 18 - 4 = 122 </u>

<u> Angle B is 18 + 4 = 22 </u>

<u> Angle D is 2 * 18 = 36</u>

<h2>Step-by-step explanation:</h2>

As we know that the sum of all angles of a triangle is 180

So adding all the angles we get

2x + x+4 + 7x-4 = 180

10x = 180

10x = 180

x = 18

In order to find each angle, put x = 18.  

 Angle C is 7 * 18 - 4 = 122

Angle B is 18 + 4 = 22

Angle D is 2 * 18 = 36

Answer:

B = 22

C = 122

D = 36

Step-by-step explanation:

The angles of a triangle add to 180. Take the measure of each angle add them together. Set them equal to 180.

2x + x + 4 + 7x - 4 = 180

10x = 180

x = 18

To find each angle, substitute x = 18.

Angle B is 18 + 4 = 22

Angle C is 7(18) - 4 = 122

Angle D is 2(18) = 36

The height H of a skydiver t seconds after jumping. Let T be the independent variable, and assume the skydiver jumps from a heig
Rina8888 [55]

Answer:

25 seconds

Step-by-step explanation:

Skydiving.  

height (in feet) above the earth=h(t)= -16t^2 + 10,000

the time it would take to fall when h is 0  

-16t^2 + 10,000=0

-16t^2=-10000

16t^2=10000

t^2=10000/16=625

t=sqrt 625=25 seconds

Identify the domain of the graph given. *Don't forget the parenthesis or brackets*​
anzhelika [568]

Answer:

(-4,3)

Step-by-step explanation:

The domain of a function is all of its possible x-values.  In this graph, there is a y-value for every x-value between -4 and 3 except -4 and 3, because there are open dots at those points.  Therefore, the domain is (-4,3).  Use parenthesis because the function is not defined at x=-4 or x=3.
