Math Problem Statement

Teorema de tales

Solution

The problem involves using the concept of similar triangles, which is related to the theorem of Thales. According to the image, there are two right triangles formed by the shadows of the statue and the pole.

Given Data:

  1. Height of the statue: 4.2 m
  2. Height of the pole: 5.8 m
  3. Length of the shadow of the statue: 3.4 m
  4. Length of the shadow of the pole: xx (unknown)

Step-by-Step Solution:

We use the theorem of Thales which states that corresponding sides of similar triangles are proportional.

From the two triangles, we can set up the proportion:

4.23.4=5.8x\frac{4.2}{3.4} = \frac{5.8}{x}

Now, let's solve for xx:

x=5.8×3.44.2x = \frac{5.8 \times 3.4}{4.2}

Calculating this value:

x4.7mx \approx 4.7 \, \text{m}

Therefore, the distance between the pole and the statue is approximately x3.4=4.73.4=1.3mx - 3.4 = 4.7 - 3.4 = 1.3 \, \text{m}.

Conclusion:

The approximate distance between the pole and the statue is 1.3 m.
