Question

Help me plz this stuff is hard

Answer 1

25.9

Explanation:

By sine rule:

`(BC)/( \sin 25 \degree) = (23)/( \sin 22 \degree) \\ \\ BC = (23 \sin 25 \degree)/( \sin 22 \degree) \\ \\ BC = (9.72022002)/( \sin 22 \degree) \\ \\BC = 25.947808156 \\ \\ BC \approx \: 25.9`

Answer 2

`x = 25.9`

Explanation:

Apply law of sines.

`(23)/( \sin(22) ) = (x)/( \sin(25) )`

`(23)/( \sin(22) ) * \sin(25) = x`

`x = 25.9`
