Question

Find c.
Round to the nearest tenth:
2 cm
15°
105

Answer 1

Answer:

0.5cm

Step-by-step explanation:

Using the sine rule

Answer 2

Answer:

c = 0.5 cm

Step-by-step explanation:

Using the Sine rule in the triangle, then

$\frac{c}{sin15}$ = $\frac{2}{sin105}$ ( cross- multiply )

c × sin105° = 2 × sin15° ( divide both sides by sin105°

c = $\frac{2sin15}{sin105}$ ≈ 0.5 cm ( to the nearest tenth )
