Question

What is the length of the altitude CD in the figure?

A. 3.3
B. 2.7
C. 2.2
D. 3.9

Answer 1

It would possibly be d as the answer

Answer 2

`x= 3.3`.

Explanation:

I am going to use Pitagoras theorem to solve it. Let's call x to the line CD. The, by Pitagoras we have that

`5^2+x^2=6^2`

`25+x^2=36`

`x^2=36-25`

`x^2=11`

`x= √(11)`

`x= 3.3`.
