C.) 68
Why?
a triangle has 180 degrees.
The tics denote the sides being equal, which means the opposite angles are equal, too. To get the remaining subtract it from 180... 180- 2(56) =68 degrees

A triangle should add up to 180 degrees.
So subtract 56 from 180 and get 124. This is an isosceles triangle so 2 sides have the same degree, which would be the bottom 2 sides in this case so 124-56=68, the answer is x=68. You can check by adding them all up:56+56+68=180 so this is correct.

The table shows the values of a function f(x).

QveST [7]

Answer:

The average rate of change is $=-4$

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

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

We want to find the average rate of change of the function represented in the table from x=-2 to x=2.

$=\frac{f(2)-f(-2)}{2--2}$

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

$=\frac{9-25}{2--2}$

$=\frac{-16}{4}$

$=-4$
