Answer: 24
Explanation:
The two triangles IFE and IHG are similar(AA Similarity).
The ratio of line IH : IF = EF : GH = 5 : 12
Therefore, 1.4x + 3 : 6.1x-6.5 = 5:12
Solve this ratio, and you'll get
16.8x+36 = 30.5x-32.5
13.7x = 68.5
x = 5
X is 5, so using X, we can find the length of HI.
30.5-6.5 = 24
Therefore, the answer is 24.
