Triangle ABC and DEF are right triangles, as shown. Triangle ABC is similar to triangle DEF. which ratios are equal to sin C?
Dafna11 [192]

Answer:

First option and Fourth option.

Step-by-step explanation:

To solve this exercise you need to use the following Trigonometric Identity:

sin\alpha=\frac{opposite}{hypotenuse}

In this case you know that:

\alpha =C

Since triangle ABC is similar to triangle DEF:

\angle C=\angle F

Let's begin with the triangle ABC.

You can identify that:

opposite=AB\\hypotenuse=AC

Then, substituing values, you get:

sinC=\frac{AB}{AC}

In triangle DEF, you know that:

opposite=DE\\hypotenuse=DF

So, substituing values, you get:

sinF=sinC=\frac{DE}{DF}

Please help I don't understand!
Diano4ka-milaya [45]

Answer:

25

Step-by-step explanation:

As the triangles within the bigger triangle are similar, the sides are in proportion.

⇒ \frac{18}{30} = \frac{15}{w}

⇒ \frac{3}{5} = \frac{15}{w}

⇒ 3w = 75

⇒ w = 25

Step-by-step explanation:

I hope you got the hang of it.

I didn't had a place to draw the verbal questions, so I just did them in my head - if you want to understand it better

I suggest that you draw those triangles
