We know that with a straight line, the resulting angle is 180.
So, knowing this:
6x+12+5x+3=180
Solve for x
11x+15=180
11x=165
x=15
Plug x back into your respective angles
Angle 1: 6(15)+12=102 degrees
Angle 2: 5(15)+3=78 degrees
Therefore angle 2 is 78 degrees.

From equation 1 :

Putting value of
in equation 2 we get :

Putting value of
in equation 1 we get :

Therefore , point of interaction is
.
Hence , this is the required solution .
A=p(1+i/m)^mn
A=6,200×(1+0.0277÷52)^(52×8)
A=7,737.59
Interest earned=7737.59-6200=1537.59
