Answer:
First option and Fourth option.
Step-by-step explanation:
To solve this exercise you need to use the following Trigonometric Identity:

In this case you know that:

Since triangle ABC is similar to triangle DEF:

Let's begin with the triangle ABC.
You can identify that:

Then, substituing values, you get:

In triangle DEF, you know that:

So, substituing values, you get:

Answer:
8/15
Step-by-step explanation:
KEEP FLIP FLIP
keep 2/5
flip the sign (multiply, not divide)
flip 3/4 to 4/3
2/5 x 4/3
8/15
Getting a 5 = 1/6
Getting tails = 1/2
1/6 * 1/2 = 1/12
Answer:
Step-by-step explanation:
when finding the slope, change in the x value is considered the RUN
slope = (y2 - y1) / (x2 - x1) = rise / run
