Finding Distance in the Coordinate Plane

Question 1 • Pre-Algebra - MA3119 B-CR

Which equations will find the distance between the lions and giraffes? Select all that apply.

Answer
A
11+16 = c
B
112+ 162 = c2
C
c2+ 162 = 112
D
121+ 256 = c2
E
11(2)+16(2) = 2c

Explanation

The distance between the lions and giraffes is the hypotenuse of a right triangle with legs 11 and 16. The Pythagorean theorem gives 11² + 16² = c², which is choice B; evaluating the squares gives 121 + 256 = c², choice D.
