Question

Need help (trigonometry) ​

Answer 1

11.9cm

Explanation:

Sin 58 degrees = opposite side/hypotenuse

Sin 58 degrees = BC/14

Sin 58 degrees = 0.848

0.848 = BC/14

0.848 x 14 = BC

BC = 11.9 cm

Answer 2

You are asked to find side BC. We can use sin of 58 to find the side

So sin 58= BC/ 14

0.848=BC/14

BC = 0.848x14

BC=11.872
