Question

1. In right triangle ABC, altitude CD is drawn to hypotenuse AB. If DB = 3

and CD = 6, find AD.

Answer 1

The value of line AD would be = 3√2.

How to calculate the missing value of the triangle?

To calculate the value of the line AD of the given triangle, the following steps should be taken as follows:

Given the following;

DB = 3

CD = 6,

Required

find AD.

using the similarity property of a triangle

DB/AD = AD/CD

3/AD = AD/6

3*6 = AD²

18 = AD²

AD = √18

AD= √9*√2

AD = 3√2

Answer 2

3√2

Explanation:

Given the following;

DB = 3

CD = 6,

Required

find AD.

using the similarity property of a triangle

DB/AD = AD/CD

3/AD = AD/6

3*6 = AD²

18 = AD²

AD = √18

AD= √9*√2

AD = 3√2

Hence the measure of AD is 3√2
