Answer:

5.66 inches

Step-by-step explanation:

{a}^{2}  +  {b }^{2}   =   {c}^{2}

a² + 7² = 9²

a² + 49 = 81

a² + 49 - 49 = 81 - 49

a² = 32

a = square root of 32

a = 5.6568 or 5.66 inches

I used the Pythagorean Theorem to solve this.

Answer:5.7inches

Step-by-step explanation:

a=√(c^2-b^2)

a=√(9^2-7^2)

a=√(9x9-7x7)

a=√(81-49)

a=√(32)

a=5.7

Is 6.52 grater then 6.520
stich3 [128]
No 6.52 is equal to 6.520.
The reason for this is because even if you add more ceros to the othe side of 6.52 it would not matter unless there is another number other than 0, Like 6.52000000000000001 is bigger than 6.52 ans smaller tahn 6.5200000000000000000000
