Question

What is the length of BC? Round to the nearest tenth.
O 14.3 in.
0 20.5 in.
O 21.3 in.
O 22.6 in.

Answer 1

Answer:

B) 20.5

Step-by-step explanation:

Answer 2

The triangle is an illustration of a right-angled triangle

The length of BC is 14.5 inches

From the figure (see attachment), the length of BC can be calculated using the following sine rule

$\sin(65) = \frac{BC}{16}$

Multiply both sides of the equation by 16

$BC = 16 * \sin(65)$

Evaluate the product

BC = 14.5

Hence, the length of BC is 14.5 inches
