Question

I want to know the length of CB is and i need help w on goin questions

Answer 1

From the given diagram, we can extract the triangle:

Required: The length of the side CB

Using Pythagoras theorem:

`Hypothenuse^2\text{ = Opposite}^2\text{ + Adjacent}^2`

Substituting the given sides:

`\begin{gathered} CB^2\text{ = CD}^2\text{ + CB}^2 \\ CB^2\text{ = 3}^2\text{ + 4}^2 \\ CB^2\text{ = 25} \\ CB\text{ = }√(25) \\ CB\text{ = 5} \end{gathered}`

Answer:

CB = 5
