<h3>Answer:   x = 29</h3>

=====================================================

Work Shown:

Focus on triangle DEC. We have angle C is 48 and D is 74. Let's find angle E.

D+E+C = 180

74+E+48 = 180

E+122 = 180

E = 180-122

E = 58

----------

In the sequences ABC and DEC, we have B and E as the second letters. The order is important because the angles must align properly (so we know how they pair up). Therefore, angle B = angle E because triangle ABC = triangle DEC.

Furthermore,

angle B = angle E

2x = 58

x = 58/2

x = 29

Enter an equation in point-slope form for the line.
Klio2033 [76]

Answer:

y + 1 = 8 (x + 7)

Step-by-step explanation:

point slope form is

y - y1 = m (x - x1)

So replace the y1 with the y point, and the x1 with the x point

y - (-1) = m (x - (-7) )

then replace the m with the slope

y - (-1) = 8 (x - (-7) )

now solve

y + 1 = 8 (x + 7)

What the answer to this equation X/8+4=5 ?
V125BC [204]

Answer:

The answer to this equation is 8

Step-by-step explanation:

\frac{x}{8} +4=5\\

<u>First: Subtract</u>

8-4=4

5 > 4 meaning that 5 is greater than 4.

You still need another number to make it equal than or greater than or equal to five.

5-4=1

Since 5 minus 4 does equal 1

You need somewhere to divide it from to get 1 so you can add up the 4 to it and get the answer to the equation.

<u>Lastly: Divide</u>

\frac{8}{8} =1

1+4=5\\5=5\\4\neq 5

Now, if you do 8/8 which equals 1, 1+4 = 5; Now everything is, <u>equaled</u> up!

<u>So in conclusion...</u>

\frac{x}{8} +4=5\\x=8\\\frac{8}{8}=1\\1+4=5\\5\neq5
