Answer 1

Answer:

3rd answer EF =  2√13

Step-by-step explanation:

Make a right triangle and use Pythagorean theorem a²+b² = c²

Go from point  F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.

Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²

36 + 16 =  52

EF² = 52 find √52

EF = √52

There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √

52 = 4 * 13

EF = √4 * √13 = 2√13
