Question

1) Find the value of x. Round to the nearest tenth, if necessary. x = _______

Answer 1

x = 34 cm

Explanation:

Using Pythagorean Theorem,

a² + b² = c²

Values given :-

a and b = 16 and 30

c = x

Substitute :-

x² = (16)² + (30)²

x² = 256 + 900

x² = 1156

x = √1156

x = 34 cm

Answer 2

x = 34

Explanation:

By Pythagoras theorem:

`{x}^(2) = {(16)}^(2) + {(30)}^(2) \\ \\ = 256 + 900 \\ \\ = 1156 \\ \\ \implies \: x = √(1156) \\ \\ \implies \: x =34`
