If ΔJKL~ΔMKN, find the value of x.

x = 14

Step-by-step explanation:

Since the triangles are similar, then the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

12(3x - 2) = 32(x + 1) ← distribute parenthesis on both sides

36x - 24 = 32x + 32 ( subtract 32x from both sides )

4x - 24 = 32 ( add 24 to both sides )

4x = 56 ( divide both sides by 4 )

x = 14

1. Lateral surface area: 7x4 = 28 inch^2

2. Total surface area: 1/2 x 3.5 x 4 x 5 = 35inch^2
