Question

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If BD = 6 and DC 2, what is the length of AD?​

Answer 1

2√10

Explanation:

when trangle ABC is drawn and then you insert ur altitude BD which is a straight line , and u then join it to c. This will form a rectangle. When that rectangle is formed you can use the available adjacent and opp which is now 6 and 2. Use this to find your hypoteneuse. Formula is x^2 + y^2 = z^2. and ur answer will be √40 which is equivalent to 2√10
