Question

Find the exact length of the third side

Answer 1

≈7.48, exact would be 7.48331477355

Explanation:

Pythagorean Theorem

c is the hypotenuse (longest side)

a and b are interchangeable

a^2 + b^2 = c^2

3^2 + 7^2 = c^2

(9 + 47 = 56)

56= c^2

`√(56)` = c

7.48 ≈ c

hope this helps :)

Answer 2

7^2 = 49
3^2 = 9
49 + 9 = 58
square root of 58 is 7.6
the answer is 7.6
