Right Triangle Hypotenuse Calculation

MathematicsTrigonometry and Right TrianglesEasy

Published:

Given the right triangle $ABC$ where:

- The angle at $B$ is $90^\circ$

- The lengths of legs $AB = 4$ and $BC = 4$

- The interior angles at $A$ and $C$ are both $45^\circ$

Find the value of $x$ (the hypotenuse $AC$).

$$x = ?$$

This question includes visual content: A hand-drawn sketch of a right triangle on grid paper. Vertex A is at the top, B at the bottom left (right angle), and C at the bottom right. The leg AB is labeled with length 4. The leg BC is labeled with length 4. The angle at C is labeled as 45 degrees, and the angle at A is also labeled as 45 degrees. There is a right-angle symbol at vertex B. The hypotenuse AC is marked with an 'x' and another expression '4\sqrt{2}', followed by 'x = ?'.

Step 1

Bu soruda, ABC dik üçgeninde hipotenüs uzunluğunu bulmaya çalışacağız. Elimizdeki verileri inceleyelim.

Dik Üçgende Kenar Bulma

Step 2

Şekilde ABC üçgeninin B açısının doksan derece olduğunu görüyoruz. AB dik kenarının uzunluğu dört birim olarak verilmiş.

Step 3

Ayrıca C açısının kırk beş derece olduğu belirtilmiş. Bir dik üçgende açılardan biri kırk beş derece ise, diğer dar açı da kırk beş derecedir.

Step 4

Bu durumda ABC üçgeni ikizkenar dik üçgendir. Yani dik kenarların uzunlukları birbirine eşittir. AB kenarı dört ise, BC kenarı da dört birimdir.
