Question

Can someone help me

Answer 1

Answer: Around 38.2°

Explanation:

• Set ∠A = x & a = 15
• Set ∠B = 27° & b = 11

Substitute them into the formula for the law of sines:

`(sinA)/(a) =(sinB)/(b) \\\\(sinx)/(15)=(sin27)/(11) \\`

Cross-multiply:

`11sinx=15sin27`

Solve for x:

`sinx=(15sin27)/(11) \\\\x=sin^(-1) ((15sin27)/(11))\\\\=38.2488`
