Question

Find the exact length of the third side.
50
30

Answer 1

40

Explanation:

The length of the third style can be found by applying pythagorean theorem.

Thus:

a² + b² = c², where,

a = 30

b = ??

c = 50 (hypotenuse/longest side)

Plug in the values into the formula.

30³ + b² = 50²

900 + b² = 2,500

Subtract 900 from each side

b² = 1,600

√b² = √1,600

b = 400
