Step-by-step explanation:
well well from your question the value of g wasn't given and we are asked to solve for f
I will have to assume g=g
make f subject of formula
first we open the brackets
-3g+6f=5g
collect like terms
6f=5g+3g
6f=8g
f=8g/6
f=(4/3)g
5-2.6= 2.4
2.4/.38= 6.316
6.316
Answer is rounded, not 100% if this is correct but that is how I would solve.
Here sin theta is positive and tan theta is negative , it means theta is in second quadrant where cos is negative too .
So the correct option is the third option .

48-10=x x=38
38x2= 76
so basically his weight is 48, which is ten more than his fathers weight, so you subtract ten from 48, giving you 38. 38 is only half the father's weight, so you double it and get 76.
