Question

Use Pythagorean Theorem to find the length of the missing side of this right triangle to the nearest tenth.

Answer 1

10.3

Explanation:

Pythagorean Theorem:

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

a and b being the sides and c being the hypotenuse.

`3.9^(2) + b^(2) = 11^(2)`

15.21 +
`b^(2)` = 121

`b^(2)` = 121 - 15.21

`b^(2)` = 105.79

b =
`√(105.79)`

b = 10.3
