go for it, math:)

Answer 7

@studyboy5255
Referring to the diagram, L=a+b
so
\(\large L=\frac{4}{\cos(\theta)}+\frac{3}{\sin(\theta)}\)
ok so far?

Answer 8

what is the angle?

Answer 9

@studyboy5255
Since you're busy, I will give you the rest of the procedure.
You can post for answer check.
Equate \(\frac{dL}{d\theta}=0\) and solve for theta.
You can solve for \(\theta\) easily by factorizing, using
\(A^3-B^3=(A-B)(A^2+AB+B^2)\)

Answer 10

The angle is between 40 and 50 degrees.
