Question

What is length of side a given the following coordinates?

A (0,0), B(3,0), and C(2, 10).
A. 10.2
B. 79
C. 10.0
D. 3

Answer 1

Answer: A. 10.2

Step-by-step explanation: For this problem we have to create a second right triangle to find the length. You can apply the pythagorean theorem which continues to 10^2+2^2=c^2 which would get us 104. Then find the root of 104 which is equal to 10.2
