Answer:
Step-by-step explanation:
sin 52 cos 13-cos 52 sin 13=sin (52-13)=sin 39
Ummm if its multiply then its 1 and 6. is its addition then its 1 and 5 or 6 and 0. if its divide it would be 6 and 1. is its subtraction then it would be 7 and 1 or 6 and 0
I hope this helps. Since there are verticale angles that’s why I added another x.

Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
