Cosα=adjacent/hypotenuse
In this case you have:
cosα=FE/DF
DF=FE/cosα, we are told that FE=13 and α=34 so
DF=13/cos34
DF≈15.68 which is
DF≈15.7 (to nearest tenth)
Answer:
247,605
Step-by-step explanation:
Each year, the population is multiplied by a factor of (1 -14.6%) = 0.854. Multiplying by that factor for 10 years gives the value ...
1,200,000×0.854^10 ≈ 247,605
The population in 1990 is predicted to be 247,605.
