The age of a person is thrice the total ages of his two daughters. 0.5 decades hence, his age will be twice of the total ages of his daughters. Then what is the father's current age? (0.5 decades = 5 years) A. 35 years
B. 40 years
C. 45 years
D. 47 years

C. 45

Step-by-step explanation:

45+5=50 (fathers age in 5 years)

50/2=25 (daughters combined age in five years)

25-5-5=15 (age now)

15*3=45 (fathers age now)

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
