Answer:

6.1 inches

Step-by-step explanation:

you are using the pythagorean theorem.

6.2^{2} + b^{2} = 8.7^{2} so 6.2 and 8.7

38.44 + b^{2} = 75.69 so 38.44 and 75.69

b^{2} = 37.25     you subtract 38.44 from both sides

\sqrt{b^{2} } = \sqrt{37.25} so b^{2} and 37.25

b = 6.103277808

so the length b is about 6.1 inches
