Step-by-step explanation:
Answer:
The answer to your question is: 111°
Step-by-step explanation:
The sum of the interior angles of a polygon is (n - 2) 180°
This polygon has 7 sides
Then n = 7
Process
120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180
120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)
789 + x = 900
x = 900 -789
x = 111°
Answer:
<h2>y = 9x + 65</h2>
Step-by-step explanation:
To find the equation of the line given the slope and a point we use the formula

where
m is the slope
( x1 , y1) is the point
From the question the slope is 8 and the point is ( - 9 , - 7)
Substitute the values into the above formula and solve for the equation
We have

We have the final answer as
<h3>y = 9x + 65</h3>
Hope this helps you
Rewrite and factor 9 and 21;
3•3+3•7= 3(3+7)
GCF for 9 and 21 is 3
