Answer:

f(1) = 31.

Step-by-step explanation:

f(n + 1) = f(n) - 3

So f(4) = f(3) - 3

22 = f(3) - 3

f(3) = 22 + 3 = 25

so f(2) = 25 + 3 = 28

and f(1) = 28 + 3 = 31.

Given rs || qp, what is the value of x?

myrzilka [38]

In the given figure,

Angle 108° + 12x = 180°

because they for pair of co- interior angles which are supplementary.

so,

$12x + 108\degree = 180\degree$

$12x = 180\degree - 108\degree$

$12x = 72\degree$

$x = \dfrac{72\degree}{12}$

$x = 6\degree$

hence , value of x = 6°
