Question

What is the length of bc ? Round to the nearest tenth.

Answer 1

Answer:

The value of BC is 14.5 cm .

Step-by-step explanation:

Now by using the trignometric identity .

$sin\theta = \frac{Perpendicular}{Hypotenuse}$

As given

$\theta = 65^{\circ}$

Perpendicular = BC = x

Hypotenuse = AB = 16 cm

$sin\theta = \frac{Perpendicular}{Hypotenuse}$

$sin\ 65^{\circ} = \frac{x}{AB}$

$0.9063\ (Approx) = \frac{x}{16}$

x = 0.9063 × 16

x = 14.5 cm (Approx)

x = BC = 14.5 cm

Therefore the value of BC is 14.5 cm .

Answer 2

I believe the answer is C 14.5
