<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

Can someone please explain expanded form with this number 15,409
Anarel [89]
The expanded form of 15,409 would be 15,000 + 400 + 9.

Your 15 would alone be 15,000. The 409 is turned into zeros.
For 409, take the 9 off of the end and keep it by itself, and then add a zero in replace for the 9, which makes 400. 
The 9 should come in at the last part as it is the last number.

Add them all together and you should get <span>15,000 + 400 + 9.</span>

What is the equation in point -slope form of a line that passes trough the points (3,-5) and (-8,4)
Ilia_Sergeevich [38]

Answer:

The equation in point - slope form of a line that passes through the points (3,-5) and (-8,4) is: y-(-5) = -(9/11) (x-3) or y+5 = -(9/11) (x-3)

Step-by-step explanation:

P1=(3,-5)=(x1,y1)→x1=3, y1=-5

P2=(-8,4)=(x2,y2)→x2=-8, y2=4

Equation in Point-Slope Form: y-y1=m(x-x1)

Slope: m=(y2-y1)/(x2-x1)

Replacing the known values:

m=[4-(-5)] / (-8-3)

m=(4+5) / (-11)

m=(9) / (-11)

m=-(9/11)

Equation in the point - slope form:

y-(-5) = -(9/11) (x-3)

y+5 = -(9/11) (x-3)
