Work out size of angle x

stiks02 [169]

Answer:

x = 105 degrees.

Step-by-step explanation:

The small polygon is a regular hexagon so each internal angle = 120 degrees while the large polygon is a regular octagon with internal angle =

135 degrees.

So angle x = 360 - ( 120 + 135)

= 360 - 255

= 105 degrees.

Note we use the fomula T = 180( n - 2) to find total internal angles in an n sided polygon. So for hexagon T = 180(6-2) = 180*4 = 720 so each internal angle in a regular hexagon = 720/6 = 120 degrees.

If f(x) = 7x- 6, which of the following is the inverse of kx)?

Yanka [14]

Step-by-step explanation:

$f(x) = 7x - 6$

$\:$

Inverse

$y = 7x - 6$

$x = 7y - 6$

$x + 6 = 7y$

$y = \frac{x + 6}{7}$

${f}^{ - 1} (x) = \frac{x + 6}{7}$
