Question

pls, help!

Answer 1

Okay, so this is quite simple. first, you would need to plug each side length in for each letter, like so 6.5^2 + b^2 = 8.5^2

Next, you would do the exponents for each number, shown below
42.24 + b^2 = 72.25

Then subtract 42.24 from 72.25, as shown below
B^2 = 30.01

Then you would take the square root of 30
b=5.47723

Answer: 5.477
