One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
The "e" just lets you know that it's scientific notation.
Answer:
1. x=60
2.x=5
3.x=8
4.x=10
Step-by-step explanation:
im assuming you want to find x value for each.
A blue whale weighs more than an African elephant by 111.5 tons
African elephant= 15,000/2,000= 7.5 tons
Blue whale weighs 238,000/2,000=
119 tons
119-7.5 = 111.5 tons
