Angle ADB is a right angle --- Given

Angle ADB is 90 degrees --- Definition of a Right Angle

Angle CDB is 90 degrees --- Definition of Supplementary Angles

Angle ADB = Angle CDB --- Definition of Congruent Angles

Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.

Hope this helps!! :)

To answer this, we let x some factor that would agree or make the ratio given true. We calculate as follows:

<span>2:3:4
2x:3x:4x

2x = 12
x = 6

What is the equation parallel to 4y-3x=8
Andreyy89

Answer:

Whatever option has a slope of 3/4 and isn't y = 3/4x + 2

Step-by-step explanation:

This means that it has to have a slope of 3/4 (written as 3/4x + b). This is because parallel lines have the same slope; rearranging the first equation gets us y = 3/4x + 2. So, our slope for a parallel line has to be 3/4.
