The sum of seven interior angle measurements is an octagon equal 835°. What is the angle measurement of the eighth angle?

creativ13 [48]

$\bf \textit{sum of all interior angles in a polygon}\\\\ S=180(n-2)~~ \begin{cases} n=\textit{number of sides}\\[-0.5em] \hrulefill\\ n=8 \end{cases}\implies S=180(8-2) \\\\\\ S=180(6)\implies S=1080$

now, we know 7 of those angles are already 835°, so the last one must be 1080 - 835 = 245°.

2. Rainey graphed a function with exponential growth and an initial value of 15. Which of the following could represent the equa

Mars2501 [29]

Exponential equation are functions defined by $y =ab^x$

The equation that could represent Rainey graph must take the form $y =15b^x$

<h3>How to determine the equation</h3>

An exponential equation is represented as:

$y =ab^x$

Where:

a represents the initial value
b represents the rate

The initial value (a) is 15.

So, the equation becomes

$y =15b^x$

The graph is not given;

So, the equation cannot be determined.

Assume that the rate is 2.

Then the function would be: $y =15(2)^x$

Solve for f <br> 0.3=0.5f-0.7

erastovalidia [21]

Answer:

f=2

Step-by-step explanation:

0.3+0.5f-0.7

Move the varibale (0.5f) to the left-hand side and change it's sign to negative.

-0.5+0.3+-0.7

Move the constant to the right hand side and change it's sign

-0.5f=-0.7-0.3

Calulate the differnce

-0.5f=-1

divide both sides by -0.5

F=2

Geometric Shapes - Part 1

Softa [21]

Answer:

x = 54, so the vertical angles are 110°.

Step-by-step explanation:

$2x + 2 = 3x - 52$

$2 = x - 52$

$x = 54$

$2(54) + 2 = 108 + 2 = 110$

$3(54) - 52 = 162 - 52 = 110$
