Hey there! :)

You have to use the Pythagorean theorem: a² + b² = c²

A = 3
3² = 3 × 3 = 9

B = 8
8² = 8 × 8 = 64

64 + 9 = 73

√73 = 8.5

Your answer is 8.5

Hope this helps :)
Hi!

Your answer is 8.5 because:

You have to use the Pythagorean Theorem: a² + b² = c²

a = 3
3² = 9 

b = 8
8² = 64

64 + 9 = 73

The square root of 73 ( rounded to the nearest tenth) is 8.5

I hope this helps you and have a wonderful day!
