Question

Laws of sines!!!!! find c. round to the nearest tenth!!! ​

Answer 1

c = 0.5 cm

Explanation:

Law of sines:

sin (15) / c = sin(105) / 2

0.2588 / c = 0.9659 / 2

c = 0.2588 * 2 / 0.9659

c = 0.5 cm

Answer 2

c=0.5 cm

Explanation:

Angle C is 15 and angle B is 105

The value of b=2cm

We need to find out 'a'

`(sin A)/(a) =(sin B)/(b) =(sin C)/(c)`

`(sin B)/(b) =(sin C)/(c)`

`(sin 105)/(2) =(sin 15)/(c)`

cross multiply it

`sin(105) c= sin(15) * 2`

Divide both sides by sin(105)

`c=(sin(15)*2)/(sin(105))`

c=0.5
