1. consider one angle of a (convex) heptagon. From that angle you can construct 7-3=4 diagonals. (-3 because we cannot create diagonals with the adjacent vertices and the angle itself )
2. 4 diagonals create 5 triangular regions. (check the picture)
3. So the sum of the measures of the interior angles of the heptagon is 180°*5=900°.
4. The measure of the remaining 7th interior angle is 900°-(120+150+135+170+90+125)°=110°.
5. The largest exterior angle is when the interior angle is the smallest.
6. The smallest interior angle is 90°, so the largest exterior angle is 180°-90°=90°
Answer: 90°
Slope = 18/6 = 3
Y-intercept = -6
Equation: y = 3x -6
Absolute value of x minus 6 is less than y
one way is to jsut make all the x's positive, then subtract them from 6 and see if they are less
sorry for confusing, just read below
(-5,1)
1>|-5|-6
1>5-6
1>-1
true
(-1,-5)
-5>|-1|-6
-5>1-6
-5>-5
false
(5,-1)
-1>|5|-6
-1>-1
false
answer is (-5,1)

Dont pay attention to this it says i need 20 characters sorry:)
The equation of Celia's exponential model is 
<h3>How to estimate the model?</h3>
The table that completes the question is added as an attachment
The y-intercept is given as:
(0,9.4)
The ratios of successive data values are calculated as:










The average of the above values is

Evaluate
b = 0.75
An exponential function is represented as:

Where
a = 9.4 as in the y-intercept (0,9.4)
b = 0.75
Substitute these values in 

Hence, the Celia's exponential model is
