What is the length of the missing side? 6.7 49 45 None of these choices are correct.

b = sqrt(45)

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and be are the legs and c is the hypotenuse

2^2 + b^2 = 7^2

4 + b^2 = 49

Subtract 4 from each side

b^2 = 49-4

b^2 = 45

Take the square root of each side

sqrt(b^2) = sqrt(45)

b = sqrt(45)

answer: add the !
