Starts at 1,000feet
Each second is getting 20 feet closer to the surface since is ascending ( going higher)
1,000/20= 100/2=50 second it takes to reach the surface
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
Answer:
Step-by-step explanation:
Evaluate 6(5-(6-5)-3) = 6(5-1-3) {first solve innermost bracket}
= 6* (5-4) = 6*1 =6
It would take him 2.5 hrs because when you divide 10 by 4 that's what you get
Because the ones place is under 5, we round down, and 392 becomes 390 when rounded to the nearest 10
