we have that

total books sold=750

self help=117

the percentage of self-help books is equal to

117/750=0.156=15.6%

Remember that

in the complete circle, the angle of 360 degrees represents the 100%

so

Applying proportion

Find out the measure of angle x for a percentage equal to 15.6%

360/100=x/15.6

solve for x

x=(360/100)*15.6

x=56.16 degrees
