The answer is nine. Hope this helped!
Answer:
115
Step-by-step explanation:
If two angles are supplementary, it means that their measures add up to 180 degrees.
So to find the measure of the other angle you would do:
180-65=115
So the other angle measures 115 degrees.
Hope this helped!
Ould help but I don’t even know the answer myself so I’m acting like I know the answer so I can move on
Answer:
This is GP with the first term of 512 and common ratio of 1/2
<u>The formula for nth term is:</u>
<u>The number of teams after the 4th round:</u>
- a₄ = 512*(1/2)⁴ = 32 teams
<u>Number of rounds to determine the champion:</u>
- 1 = 512*(1/2)ⁿ
- 2⁰ = 2⁹*2⁻ⁿ
- 0 = 9 - n
- n = 9 rounds
