Answer:

5.66 inches

Step-by-step explanation:

[tex] {a}^{2} + {b }^{2} = {c}^{2} [/tex]

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
