Answer 1

Answer:

$x = 7$

Step-by-step explanation:

Given

The attached figure

Required

Find x

Since both shapes are similar, then:

$LM : KN = RV : SP$

This gives:

$4x + 4 : 7x - 9 = 48 : 60$

As fraction:

$\frac{4x + 4 }{ 7x - 9} = \frac{48 }{ 60}$

Simplify:

$\frac{4x + 4 }{ 7x - 9} = \frac{4 }{ 5}$

Cross Multiply:

$5(4x + 4) = 4(7x - 9)$

$20x + 20 = 28x - 36$

Collect Like Terms

$28x - 20x = 20 + 36$

$8x = 56$

$x = 7$
