Answer:
745.31
Step-by-step explanation:
1. 12.5^2 * 2 = 312.5
2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
Answer:
Infinitely many solutions
Step-by-step explanation:
x+y=3
2x+2y=6
x=3-y
2(3-y)+2y=6
6-2y+2y=6
6+0=6
6=6
infinitely many solutions
Answer:
The length of BC = 12
Step-by-step explanation:
c^2 = a^2 + b^2
15^2 = 9^2 + b^2
225 = 81 + b^2
b^2 = 225 - 81
b^2 = 144
b = 12
The length of BC is 12
They are same side interior!! Not alternate, they’d be on opposite sides of the line
