Step-by-step explanation:
When a point is rotated 180 degrees, you take the opposite of the coordinates.
i.e (5, 6) ---> (-5, -6)
Answer:
D) Square root of 48
Step-by-step explanation:
We have to split the triangle in half and then multiply that by two for the answer. Then we use a²+b²=c² because the two triangles are right triangles, and we know b=4 and c=8, so a²+(4²)=8², or a²+16=64
a² would have to equal 48. a=√48.

Answer:
interior angle of a heptagon = 900 degrees
900 = 4x + (3x + 60)
840 = 7x
840/7 = 120
X = 120
120 X 4 = 480
120 X 3 = 360
480 + 360 + 60 = 900
4 angles = 120 degrees each
3 angles = 140 degrees each
