Set up a system of equations.
x + y = 7
5x + 6y = 39
x + y = 7
x = -y + 7
Substitute -y + 7 into the 2nd equation for 'x':
5(-y + 7) + 6y = 39
Distribute 5:
-5y + 35 + 6y = 39
Combine like terms:
y + 35 = 39
Subtract 35 to both sides:
y = 4
Plug this into any of the two equations to get 'x'
x + y = 7
x + 4 = 7
Subtract 4 to both sides:
x = 3

In this question, we have to use the intersecting chord theorem, and the formula which is
In the given circle, values of AP, CP and DP are 12m, 6m and 5m respectively .
Substituting the values in the formula, we will get
Dividing both sides by 5
