Look at the right triangle abc: right triangle abc has a right angle at b. segment bd meets segment ac at a right angle. a student made the following chart to prove that ab2 + bc2 = ac2: first one is the statement and the second one is the justification 1. triangle abc is similar to triangle bdc 1. angle abc = angle bdc and angle bca = angle bcd 2. bc2 = ac • dc 2. bc ÷ dc = bc ÷ ac because triangle abc is similar to triangle bdc 3. triangle abc is similar to triangle abd 3. angle abc = angle adb and angle bac = angle bad 4. ab2 = ac • ad 4. ab ÷ ad = ac ÷ ab because triangle abc is similar to triangle adb 5. ab2 + bc2 = ac • ad + ac • dc = ac (ad + dc) 5. adding statement 1 and statement 2 6. ab2 + bc2 = ac2\ 6. ad + dc = ac what is the first incorrect justification?

The first incorrect justification is in step 2.

Step-by-step explanation:

Step 2. BC2 = AC • DC  

2. BC ÷ DC = BC ÷ AC because triangle ABC is similar to triangle BDC

It's supposed to be AC ÷ BC not BC ÷ AC.

Justification 2

Step-by-step explanation:

I took the test and it was correct

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
