Answer: 147 Degrees
Step-by-step explanation
The size of the final unknown interior angle in a polygon is 147 degrees.
Given that,
The other interior angles are 162°, 115°, 120°, 148° and 85°.
We assume that there is an equation (2n - 4) 90.
Here n be 7.
Based on the above information, the calculation is as follows:
= (2n - 4) 90
= ((2) (7) - 4) 90
= 10 (90)
= 900
Now the size of the unknown interior angle is
= 900-(162+125+148+105+98+115)
= 900 - 753
= 147°
Therefore we can conclude that the size of the final unknown interior angle in a polygon is 147 degrees.
Answer:
Spencer and Abigail are correct
Lauren is incorrect
Step-by-step explanation:
Spencer and Abigail are correct
Slope = change in y ÷ change in x
Or
Let = (3, -1)
Let = (5, 4)
This is Spencer's method
Let = (5, 4)
Let = (3, -1)
This is Abigail's method
It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.
Lauren's calculation is wrong as she calculated her slope as:
where it should have been

i hope this helps its kind of hard to see but i tried lol
