Answer:
D. 10
Step-by-step explanation:
We can use similar triangles to solve this question. ΔRSE ≅ ΔFGE by SAS. We can set up this similarity equations: . Plugging in the numbers from the diagram, we get . Using cross multiplication, we get the following equation:
Our final answer is D. 10
As the triangles are similar :
45/55 = (12x - 3)/143
9/11 = (12x - 3)/143
9 x 13 = 12x - 3
12x = 117 + 3
12x = 120
x = 10
the awnser to your question is 48 because you are just subtracting
