Answer:
The father is 50 and his son is 15.
Step-by-step explanation:
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)
the side x is 15
bottom right angle is 31.61 degrees
other angle is 58.39 degrees
I don't know about the top half but I know the bottom half. P.S. I'm sorry
