Question

What is the length of side BC? Round your answer to the nearest tenth.

Answer 1

2 units

Explanation:

B = (3,1)

C = (1,1). ________________

Length of a line = √{( x2 - x1)² + (y2 - y1)²}

x1 = 1

x2 = 3

y2 = 1

x2 = 1

Substituting... __________

Length of BC = √{(3-1)² + (1-1)²}

= √(2)²

= 2 units
