Answer:

48 degrees

Step-by-step explanation:

First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.

Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.

Answer:

Step-by-step explanation:

Your intervals are x=-2, and x=0. In this case, x=-2 will be a, and x=0 will be b.

To find the average rate of change, you have to first find f(-2) and f(0)

$f(-2)=1-3(-2)^2\\f(-2)=1-3(4)\\f(-2)=-11\\$

Then, f(0)

$f(0)= 1-3(0)^2\\f(0) = 1-3(0)\\f(0) = 1$

Now you know f(-2) is -11, and f(0) is 1.

Next, you plug these into the average rate of change formula, which is

$\frac{f(b)-f(a)}{b-a}$

Flug in -11 and 1 on the numerator, and -2 and 0 on the denominator.

$Average = \frac{(1)-(-11)}{(0)-(-2)} \\\\$

$Average =\frac{12}{2} \\Average = 6$
