For the parabolic arch, use the below variables for load and geometry to determine the bending moment at $0\mathrm{.}59$L$?$

Point Load $1$ P$1=5\mathrm{.}1$ kN

Point Load $2$ P$2=10\mathrm{.}0$ kN

Span L $=12\mathrm{.}7$ m

Arch Rise H $=4\mathrm{.}0$ m

Location of P$1=0\mathrm{.}29$L

Location of P$2=0\mathrm{.}79$L

Give your answer in kNm to two decimal places, where a positive bending moment indicates sagging on the internal face of the arch, and a negative bending moment indicates a hogging moment on the outside face of the arch. The answer should be $1\mathrm{.}45$ however I do not know how to get to this answer.
