Answer:

Step-by-step explanation:

So in forth-fifth grade you had to learn that a straight line is 180 degrees right? So the first thing that you do is you add 65+65 and then you get 130 degrees. But we're not done yet. Now we have to subtract 180 - 130 and you get 50 degrees. So the answer is 50 degrees.

Answer:

49145 years

Step-by-step explanation:

In a certain country the life expectancy for women in 1990 was 45 and in 2000 it was 85?years.

Assuming that life expectancy between 2000 and 2100 increases by the same percentage as it did between 1900 and 2000,what will life expectancy be for women in 2100?

In 10 years, the expectancy increased by 85/45 = 17/9

between 2000 and 2100, it will increas by 10 time 10 years, so expected expectancy is $85*(\frac{85}{45})^{10} = 49145$ years
