Answer:
Complementary angles are two angles that add up to 90 degrees.
Example: 45 + 45 = 90 are complimentary
60 + 30 = 90 are complimentary
Answer:
210 km
Step-by-step explanation:
90 * 2 is 180 (distance over 2 hours)
20 minutes is .333 hours, so 90*0.333 is about 30 km
and 180+30 is 210.
Well, think of it this way... The rocket is traveling 21,000 miles for every 60 min.
So, divide 21,000 by 60 and you get 350. So, it travels 350 miles per minute, or every 60 seconds. 350 divided by 60 seconds is 5.833333333. So, your answer would be 5.8
