<h3>
Answer: a = 100</h3>
=============================================================
Explanation:
There are n = 7 sides to this polygon (so it's a heptagon)
The interior angles add up to 180(n-2) = 180*(7-2) = 900 degrees.
So that means,
69+284+62+62+242+81+a = 900
800+a = 900
a = 900-800
a = 100
Answer:
-1
Step-by-step explanation:
The line goes down 1 grid square for each grid square to the right. Each grid square represents 1 unit in both the x- and y-directions. That means the slope is ...
m = rise/run = -1/1 = -1
The slope of the line is -1.
Answer:
By taking (-1, 1) and translating it left by 2 and up by D we have (-3, 1+D)
Rotating 90° counterclockwise puts a negative on your y-coordinate and switches the x and y-coordinates.
Final answer:
(-1-D, -3)
