Question

Find the missing side length, and round to the nearest tenth if necessary.

Answer 1

3.2

Explanation:

`a^(2)` +
`b^(2)` =
`c^(2)`

a = 3

b = 1

`3^(2)` +
`1^(2)` = 9 + 1 = 10

`c^(2)` = 10

c =
`√(10)`

c = 3.16227766017

Round to the nearest tenth

c = 3.2

Answer 2

3.2

Explanation:

→ State Pythagoras theorem

x² + y² = z²

→ Substitute in

3² + 1²

→ Simplify

10 = z²

→ Evaluate

√10 = 3.2
