Answer 1

Answer: 7cm

Explanation:

Using Pythagoras Theorem (Pythagorean Theorem), the equation to find the hypothenuse (side c) of a triangle is
`a^(2)`+
`b^(2)`=
`c^(2)`

In this case the hypothenuse is 11 cm and side b is 6cm.

therefore,
`a^(2)`+
`6^(2)`=
`11^(2)`

make a the subject
`a^(2)` =
`11^(2)` -
`6^(2)`

`a^(2)` = 85

a = 9.23 (nearest hundredth)
