Answer:
a. 100
b. 156
Step-by-step explanation:
a.
(n - 2)180 = (6 - 2)180 = 4(180) = 720
? + 166 + 108 + 121 + 135 + 90 = 720
? = 100
b.
(n - 2)180 = (8 - 2)180 = 6(180) = 1080
? + 128 + 99 + 161 + 113 + 142 + 146 + 135 = 1080
? = 156
Answer:
Y-coordinate = y - 4
Step-by-step explanation:
In the given question point D coordinate is (x, y)
and D after translation
x goes to 6 unit to the right and y goes to 4 unit down.
Hence,
Y-coordinate = y-4
Example:From graph
Let point D coordinate (x , y) = (2 , 3)
After rotation
D coordinates is (x+6 , y-4) = (2+6 , 3_4) = (8 , -1)
