1. ~ ABC=
2. AB/AD=BC/?
3. 3/9=x/?
4. x=
5. scale factor of ADE to ABC
Please give full answers

Answer 1

1. ~ ABC = 180 degrees

2. AB/AD = BC/AC

3. 3/9 = x/6

4. x = 2

5. The scale factor of ADE to ABC is 1:2.

Explanation:

1. ~ABC = 180 degrees means that the sum of all the angles of a triangle add up to 180 degrees.

2. AB/AD = BC/AC means that if two sides of a triangle are divided by another side, the ratio will be the same for both sides of the triangle.

3. 3/9 = x/6 means that if you divide 3 by 9, you can find out what x is when it is divided by 6.

4. x = 2 means that when 3 is divided by 9 and the result is divided by 6, the answer is 2.

5. The scale factor of ADE to ABC is 1:2 means that ADE is twice the size of ABC and all related measurements between the two triangles are in a proportion of 1:2.
