The sum of the 3 angles needs to be 180.
To find the third angle subtract to the known angles from 180.
180 - 48 - 71 = 61
The third angle is 61 degrees.
Answer:
The number of years that will the two villages have the same number of residents is 61 years
Step-by-step explanation:
Let's assume number of years as 'x'
First Pond:
Fresh pond has a population of 854
and it’s increasing by 3 people per year
so, we can find equation for population of first pound
Second pond:
Strawberry has a population of 427
and it’s increasing by 10 people per year
so, we can find equation for population of first pound
Since, populations are equal
so, we can set both equation equal and then we can solve for x
So,
The number of years that will the two villages have the same number of residents is 61 years
Answer: The third option, 6.
