Answer:

<AXC = 101 degrees.

Step-by-step explanation:

The question says that XB is a bisector which means that <AXB = 1/2 of AXC

You can't do the question if that assumption isn't true.

<AXC = 8x - 7

<AXB = 3x + 10

3x + 10 = 1/2 ( 8x - 7) Multiply both sides by 2

2(3x + 10) = 8x - 7 Remove the brackets

6x + 20 = 8x - 7 Add 7 to both sides

6x + 20 + 7 = 8x Combine

6x + 27 = 8x Subtract 6x from both sides

27 = 8x - 6x Combine

27 = 2x Switch

2x = 27 Divide by 2

x = 27/2

x = 13.5

AXC = 8x - 7

AXC = 8*13.5 - 7

AXC = 108 -7

AXC = 101

What is the quotient of m^6/5 divided by 5/m^2

DENIUS [597]

Answer:

$\large\boxed{\dfrac{m^8}{25}}$

Step-by-step explanation:

$\dfrac{m^6}{5}\div\dfrac{5}{m^2}\\\\\text{Divide by a fraction is the same as multiply by its reciprocal}\\\\=\dfrac{m^6}{5}\times\dfrac{m^2}{5}=\dfrac{m^6\times m^2}{5\times5}\\\\\text{use}\ a^n\times a^m=a^{n+m}\\\\=\dfrac{m^{6+2}}{25}=\dfrac{m^8}{25}$
