Question

Suppose that you have measured a length of 6 cm on one board and 8 cm on the other. You would adjust the two boards until the length of the string had value c to ensure that the boards made a right angle. What is c? Express your answer in centimeters to three significant figures.

Answer 1

c = 10.000cm

Explanation:

If the 2 boards made the right angle, c would be the hypotenuse with 2 sides of 6 cm and 8 cm. We can then use Pythagorean formula to solve for c

`c^2 = 6^2 + 8^2 = 36 + 64 = 100`

`c = √(100) = 10.000 cm`
