What is the length of vw? a. 16 units b. square root of 13 units c. 20 units d. square root of 20 units

The answer is D. If you make a right triangle with the line, then you can use the Pythagorean theorem (a^2+b^2=c^2) to solve for VW. The vertical line would be 4 units and horizontal line would be 2 units. Therefore 4^2+2^2=20 take the square root of 20 and that is the answer.

The answer is “faster”.
