Answer:
12.9
Step-by-step explanation:
cos 72 = 4/x
x = 4/cos72
x = 12.9
The answer is 8
Because 20%*40=8
![40 \div 100 \times 70 \\ 4 \times 7 = 28 \\ 70 - 28 = 42](https://tex.z-dn.net/?f=40%20%5Cdiv%20100%20%5Ctimes%2070%20%5C%5C%204%20%5Ctimes%207%20%3D%2028%20%5C%5C%2070%20-%2028%20%3D%2042)
Step-by-step explanation:
First find 40% of 70, which is 28
Then subtract the 28 from 70 to find the goals scored by the rest of the team
10x10x10 1,000 thats the answer i guess
X = 8.66
using pythagorean theorem u will get 8.66
