Sum of all interior angles of a polygon
180( n - 2) where n = number of sides in the polygon
now, if n = 19, the polygon has 19 sides, then 180( 19 - 2)
Answer:




Step-by-step explanation:
<u>Given information</u>



<u>Derived expression from the given information</u>
<em>Presumably, I think this is a combination of segments</em>

<u>Substitute values into the given expression</u>

<u>Combine like terms</u>
<em>The following is the expression</em>

<u>Subtract 3 on both sides</u>


<u>Subtract x on both sides</u>


<u>Substitute the x value into corresponding expressions to determine the final value</u>


Hope this helps!! :)

This is the concept of geometry, for us to get the value of JM we will requires to get the value of x first;
From the diagram we have been told that;
KL=ML
KL=7x+7
ML=8x-3
thus;
8x-3=7x+7
collecting the like terms we get;
8x-7x=7+3
x=10
But, JM=13x+2
substituting the value of x in JM we get:
JM=13(10)+2
JM=130+2
JM=132
The answer is 132°
Petra is 13 and her mother is 32. I used this equation:

if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.
