Answer:
12
Step-by-step explanation:
Use the distance formula to find the value of the side lengths.
d=√((x1-x2)²+(y1-y2)²
d of side AC is 6
d of side CB is 10
Angela's use of the Pythagorean Theorem of 10²+6²+c² is incorrect; she put the right values in the wrong spots, the formula needed is:
6²+10²=c²
Option C- Angelica's side lengths were too long.
15.8 as the square root of (13^2+9^2) is less then the square root of (10^2+14^2) you can do this by using the Pythagorean Theorem.
