Question

Please answer! Solve for X

Answer 1

Answer:

x = 3

Step-by-step explanation:

We can solve this by using ratios of similar triangles

3           x

------ = ------------

3+9           12

3           x

------ = ------------

12           12

x must equal 3 to keep the ratios the same

Answer 2

Answer: x = 3

Step-by-step explanation:

The question involves two triangles,

Big triangle AED,

small triangle ABC.

Both triangles are similar and

AED has base of 9 + 3 = 12 and heught of 12

ABC has base of 3 and height of x

To find x we equate the ratios of their height to their base

x/3 = 12/12

x/3 = 1

x = 3
