Question

Solve for x using the given diagram

Answer 1

Answer:

x = 1

Step-by-step explanation:

Look a t the picture.

The triangles on the picture are similar.

Therefore the sides are in proportion:

$\dfrac{8x}{10}=\dfrac{4}{5x}$              cross multiply

$(8x)(5x)=(4)(10)$

$40x^2=40$           divide both sides by 40

$x^2=1\to x=\sqrt1\\\\x=1$
