Respuesta :

Answer:

It s the second option.

Step-by-step explanation:

1.  Altitude.

2.  a.sinB

3.  b.sin A = a. sin B.

1. altitude

2. a sin B.

3. b sin A =   a sin B.

What is reflexive property?

The reflexive property of equality states that a number is always equal to itself.

As, per the diagram, triangle ABC with altitude CD labelled x.

Using the trigonometric ratio

s sin A= X/b and sin B= X/a

Multiplying to isolate x in both equations gives

x=b sin A and x= a sin B.

By the substitution property b sin A =   a sin B.
