Question

In the diagram, BC = 12 /. Find AB. Write your answer in simplest form.B450O AB = 24O AB = 12VO AB = 24 2O AB = 12

Answer 1

Given data:

The given right angle triangle.

The expression for cos(45°) is,

`\begin{gathered} \cos (45^(\circ))=(BC)/(AB) \\ \frac{1}{\sqrt[]{2}}=\frac{12\sqrt[]{2}}{AB} \\ AB=24 \end{gathered}`

Thus, the value of AB length is 24.
