Question

Sin law or cos law?!!!!!!!!!!!!! ​

Answer 1

Law of Sines

Explanation:

Law of Sines:
`(A)/(sina) =(B)/(sinb) =(C)/(sinc)`

Step 1: Solve for m∠B

`(25)/(sin36) =(27)/(sinx)`

25sinx = 27sin36°

sinx = 27sin36°/25

`x = sin^(-1)((27sin36)/(25) )`

m∠B ≈ 39.4°

Step 3: Find m∠C

180 - (36 + 39.4)

180 - 75.4

m∠C = 104.6°
