Answer:
0.127
Step-by-step explanation:
|√15-5+1 |
|√15-4 |
|3.873-4 |
|-0.127|
0.127
Join JH and KH.
You did that so you could measure or calculate the size of <JHK. There are 5 such central angles in a pentagon. If you drew a little circle with H as the center and you went around the circle once, you would have traveled 360 degrees. So <JHK = 360/5 = 72. Make sure you understand that before you read on.
Ok here's the trick. 144 = 2*72. That means that when you rotate the pentagon, you rotate it through Two central angles.
What will happen is that Point J will wind up at Point L and Point K will sit where N is right now. All the points not mentioned will do the same thing. They will move two points clockwise.
so 3 tenths is 0.3 and 5 tenths is 0.5 but if you need to add them you would get 0.8
1:
5w + 5 + 4w + 8 = 130
9w + 13 = 130
9w = 117
w = 13
2 is C
3:
3x - 4 + 8x - 14 = 180
11x -18 = 180
11x = 198
x = 18
54 - 4 = 50 (angle 1)
130 (angle 2)
