Q:

The triangles are similar.What is the value of x?Enter your answer in the box.x =

Accepted Solution

A:
Answer:x =16Step-by-step explanation:You can use Theorem Pythagoras method to solve this question.The formula is a^2 + b^2 =c^2In this question a=x , b=12, and c= 20to find a which means x you should use this formula : c^2 - b^2=20^2-12^2 = 400 - 144 =√256 =16You also can use another method by using the second diagram.In that diagram you have to know that 12÷3 is 4, 20÷5 is 4, hence x÷4 is 4so , x=16.I hope this two ways for answering this question will be helpful for you.
