PLZZZZZZ NEED HELP!!!!!!!!

Answer 1

5.5

Step-by-step explanation

We can use the cosine rule to find the missing side length.

The cosine rule is given as;

`{a}^(2) = {b}^(2) + {c}^(2) - 2bc \cos( A)`

Let the missing side be "a".

Then,

`{a}^(2) = {9}^(2) + {6}^(2) - 2 * 9 * 6 \cos(37 \degree)`

`{a}^(2) = 81+ 36- 86.253`

`{a}^(2) = 30.74736`

`a = √(30.747)`

`a \approx5.5`

Therefore the missing side length is approximately 5.5 units to the nearest tenth.
