Step-by-step explanation:
tan x =42/38
tan x= 1.105
x= 47.86

Answer:
The father is 50 and his son is 15.
Double the tens digit of the father's age = 10
Plus 5 = 15 (the age of the son)
50 + 15 = 65 (the sum of their ages)
The reverse of the digits of the son's age is 51.
Subtract 1 = 50 (the age of the father)
Hope this helps :)
