You need to post a graphic. I tried drawing my own, but I do not know where point "P" is nor where point "R" is.
Are you trying to solve the whole problem
To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be

. After correctly solving the problem with this equation, you will figure out that the answer is 79.
mHJ= 79°
Hope this helped :)
Answer:
son age: X
man_age= 5X
in 3 years: we have: (man_age+3)(X+3)=380
we can replace the man age by 5X and we get :
(5X+3)(X+3)=380
it is a quadratic equation with 2 solutions. One negative and 7
The solution is thus 7, since age can not be negative.
The son is thus 7 and the dad 5 times more 35
