Question

Use the law of sines to find the length of side c (answer as soon as possible)

Answer 1

21.28

Explanation:

Answer 2

D

Explanation:

Using the law of sines in ΔABC, then

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

Substituting in values gives

`(c)/(sin31.6)` =
`(25)/(sin38)` ( cross- multiply )

c × sin38° = 25 × sin31.6° ( divide both sides by sin38° )

c =
`(25(sin31.6))/(sin38)` ≈ 21.28 → D
