Answer:

19

Step-by-step explanation:

Since these two are vertical angles, their measure must be equal. Therefore:

3x-3=6(x-10) \\\\3x-3=6x-60 \\\\3x+57=6x \\\\3x=57 \\\\x=19^{\circ}

Hope this helps!

Answer:

19

Step-by-step explanation:

The two angles are vertically opposite angles, so they are equal.

3x - 3 = 6 (x - 10)

3x - 3 = 6x - 60

3x - 6x = - 60 + 3

-3x = -57

x = -57/-3

x = 19

Using derivatives, it is found that the x-values in which the slope belong to the interval (-1,1) are in the following interval:

(-15,-10).

<h3>What is the slope of the tangent line to a function f(x) at point x = x0?</h3>

It is given by the derivative at x = x0, that is:

m = f^{\prime}(x_0).

In this problem, the function is:

f(x) = 0.2x^2 + 5x - 12

Hence the derivative is:

f^{\prime}(x) = 0.4x + 5

For a slope of -1, we have that:

0.4x + 5 = -1

0.4x = -6

x = -15.

For a slope of 1, we have that:

0.4x + 5 = 1.

0.4x = -4

x = -10

Hence the interval is:

(-15,-10).
