Question

Find c. Round to the nearest tenth.

Answer 1

Answer:

c ≈ 9.7

Step-by-step explanation:

Using the Sine rule in the triangle, that is

$\frac{c}{sin82}$ = $\frac{8}{sin55}$ ( cross- multiply )

c × sin55° = 8 × sin82° ( divide both sides by sin55° )

c = $\frac{8sin82}{sin55}$ ≈ 9.7 ( to the nearest tenth )
