Triangle HIJ is similar to triangle LMN. Side LM measures x + 1, side MN measures 2x and side NL measures 3x – 2. Side HI measures 12 and side IJ measures 20. Find the value of x.

Question

nurali · Answer

Since ΔHIJ is similar to ΔLMN 
LM/HI = MN/IJ = NL/JH 
(x+1)/12 = 2x/20 
Cross Multiply
20(x+1) =12*2x 
20x + 20 = 24x 
4x = 20 
x = 5
