Answer:

Step-by-step explanation:
<em><u>Identity Used </u></em>: 

Sine is the opposite to the hypotenuse
so if sinA=0.6, suppose the opposite is 6, the hypotenuse is 10
now find the other leg by using a²+b²=c²: 6²+b²=10², b=8
sinB=8/10=0.8

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
years
Solve 10x = 4.1 for x. Divide both sides of this equation by 10: x = 4.1 / 10.
x = 0.41
