Question

Identify the side lengths of the triangle.

Answer 1

$4x + 16 = 8x - 4 \: \: \: \: \: {shown \: in \: fig.} \\ 16 + 4 = 8x - 4x \\ 20 = 4x \\ x = \frac{20}{4} \\ x = 5$
put the value of x

$5x + 7 \\ 5 \times 5 + 7 \\ 25 + 7 \\ 32$
$8x - 4 \\ 8 \times 5 - 4 \\ 40 - 4 \\ 36$
$\\ 4x + 16 \\ 4 \times 5 + 16 \\ 20 + 16 \\ 36$

36,36,32
