Answer:
4 is the coordinate of A, and 12 is the length of the line from C to A
Step-by-step explanation:
Given:
coordinate of C is -8 and T is 16
the midpoint is A
coordinate of A = (C + T)/2
A = (C + T)/2
A= ( -8 + 16 )/2
A = ( 8 )/2
A = 4
CA = length of line from C to A(?)
CA = | C | + | A |
CA = | -8 | + | 4 |
CA = 8 + 4
CA = 12
