Answer:
An angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle. The interior or internal bisector of an angle is the line, half-line, or line segment that divides an angle of less than 180° into two equal angles.
Step-by-step explanation:
1. s-13=63 76
2. m-7=73 80
3. 8+m=17-10 0
4. 17+m=80 63
5. Q+25=50-11 14
6. n-18=74 92
7. n+6=82 76
8. n+3=77 74
9. 8x=72 9
10. 2x=15+9 12
The elements you can see in the reaction are Calcium(Ca), Hydrogen(H), and Oxygen(O). So there are 3 elements in the chemical reaction.
