Question

Can anyone help with number 3??Indicate the law, then find each missing measure to the nearest tenth

Answer 1

3)

Apply LAW OF SINES

`(a)/(sinA)=(b)/(sinB)=(c)/(sinC)`

Replace with the values given:

`\frac{18}{sin\text{ }112}=\frac{8}{sin\text{ }x}`

Cross multiply

`18(sinx)=8(sin112)`
`18(sinx)=7.4`
`sinx=(7.4)/(18)`
`x=arcsin((7.4)/(18))`

Answer:

x = 24.3
