It has been proved that the 5 star vertices have their sum of angles as A + B + C + D + E = 180°
<h3>How to find the sum of angles of a polygon?</h3>
The adjoining star contains a regular pentagon. Thus;
Sum of interior angles of the pentagon = (5 - 2) * 180 = 540°
Thus;
Each interior angle of the pentagon = 540/5 = 108°
Thus, each exterior angle = 180 - 108 = 72°
Then measure of the angle at the vertex = 180 - 72 - 72 = 36°
Thus, each angle at the vertices of the star have an angle of 36°.
There are 5 star vertices and so;
Sum of angles of 5 star vertices = 5 * 36 = 180°

Answer:
--- Slope intercept
--- Point slope
Step-by-step explanation:
Given
Perpendicular to 
Required
Determine its equation
The general form of an equation is:

Where

By comparison:

Next, we calculate the slope of L.
Because L is perpendicular to
, the relationship between their slopes is:

Substitute 4 for m

The equation of L in slope intercept form is: 
Substitute -1/4 for m

In point slope form, we have:

Substitute -1/4 for m

Step-by-step explanation:
Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

Addition and subtraction requires that we find a common demoninator.
For example,

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

Then we add the numerators

Then we should reduce.

Division is a little trickier because we have to flip-flop the second term and then multiply. For example: 
.875 .88 .98
7/8, 9/9, .98 is your answer from least to greatest!
