Answer 1

`\boxed{\sf x = 11.7}`

`\boxed{\sf b = 9.4}`

Sine Rule states:

`\sf sin(x) = (opposite)/(hypotenuse)`

`\hookrightarrow \sf sin(51) = (x)/(15)`

`\hookrightarrow \sf x = 15sin(51)`

`\hookrightarrow \sf x = 11.657 \ \ \approx \quad 11.7`

Additional, cosine rule:

`\sf cos(x) = (adjacent)/(hypotenuse)`

`\hookrightarrow \sf cos(51) = (b)/(15)`

`\hookrightarrow \sf b = 15cos(51)`

`\hookrightarrow \sf b = 9.4398 \quad \approx \ \ 9.4`
