Find the value of x of a octagon with a degree of (16x+23)

1 answer:

3 0

Total degrees of an octagon:
180° x (8 sides - 2)
= 1080°
8 corners of an octagon
Each corner has an angle
1080 / 8 = 135°

16x + 23 = 135
16x = 112
x = 7

If a=b-2x/x+c,then what is the value of x in terns of a,b & c ?

valina [46]

Answer:

$x=\frac{b-ac}{a+2} ; a\neq -2$

Step-by-step explanation:

Multiply both sides: by x+c

a(x+c)= $\frac{b-2x}{x+c}$ (x+c)

Simplify: a(x+c)=b-2x

Expand: ax+ac=b-2x

Subtract ac from both sides: ax+ac-ac=b-2x-ac

Simplify: ax=b-2x-ac

Add 2x to both sides: ax+2x=b-2x-ac+2x

Simplify: ax+2x=b-ac

Factor ax+2x: x(a+2)

x(a+2)=b-ac

Divide both sides by a+2: $\frac{x(a+2)}{a+2}$ = $\frac{b}{a+2}$ - $\frac{ac}{a+2}$ ; a≠-2

Simplify: $x=\frac{b-ac}{a+2} ; a\neq -2$

Answer:

To find m ( slope) we'll use the Slope Formula:

$\boxed{\sf{Slope\:(m)}=\cfrac{y_2-y_1}{x_2-x_1}}$

Subtract the numbers:-

$\sf 7. \:m=\cfrac{4-2}{6-5} =\boxed{2}$

_______________

$\sf 8.\: m=\cfrac{-1-3}{2-6} =\boxed{1}$

_______________

$\sf 9.\: m=\cfrac{-4-(-2)}{3-1} =\boxed{-1}$

_______________

$\sf 10.\: m=\cfrac{0-3}{0-(-3)} =\boxed{-1}$

_______________

$\sf 11.\:m=\cfrac{4-2}{3-1} =\boxed{1}$

_______________

$\sf 12.\: m=\cfrac{1-7}{2-5} =\boxed{2}$

_______________

$\sf 13.\:m=\cfrac{11-9}{1-(-4)} =\boxed{\frac{2}{5}}$

_______________

$\sf 14.\:m=\cfrac{2-3}{3-5} =\boxed{\frac{1}{2}}$

_______________

$\sf 15.\: m=\cfrac{11-5}{2-9} =\boxed{-\frac{6}{7}}$

_______________

$\sf 16.\: m=\cfrac{-7-\left(-6\right)}{8-13}=\boxed{\frac{1}{5}}$

_______________

$\sf 17.\: m=\cfrac{4-4}{6-1} =\boxed{0}$

_______________

$\sf 18. \: m=\cfrac{2-(-7)}{5-5}=$
