Dafna1 [17]

Answer:

40 feet

Step-by-step explanation:

Required:

Find the length of Samson's shadow

The question can be illustrated with the attached figure where Samson's shadow is represented with x.

To solve for x, we make use of the following equivalent ratios:

$18.75 : 120 = 6.25 : x$

Convert to fraction

$\frac{18.75}{120} = \frac{6.25}{x}$

Cross Multiply

$18.75 * x = 120 * 6.25$

$18.75 * x = 750$

Make x the subject

$x =\frac{750}{18.75}$

$x =40$

Hence, Samson's shadow is 40ft

The legs of a right triangle measure 6 and sqrt(x). The

hichkok12 [17]

Answer:

The value of x is 64

Step-by-step explanation:

Given:

Length of the Legs of the triangle = 6 and √x

Hypothenus = 10

Required

Find x?

The legs of a rectangle is what is regarded to as the adjacent and the opposite sides of the triangle.

Assuming the following

Adjacent = 6 and Opposite = √x

We can then solve the given example using Pythagoras theorem as foloes;

$Hyp^2 = Opp^2 + Adj^2$

By substituting 10 for Hyp; 6 for Adj and √x for Opp

$10^2 = 6^2 + (\sqrt{x})^2$

Simplify

$100 = 36 + z$

Collect Like Terms

$x = 64$ $x = 100 - 36$

Hence, the value of x is 64
