Answer:

Both triangles are right triangles because the angle d is 90 degrees in both sides

3 ^ 2 - 2.25^2 = 1.98

4^2 - 1.98^2 = 3.48

x = 3.48

Answer:

You would need to use the Pythagorean Theorem

Step-by-step explanation:

First, you would want to take the Hypotenuse of 3 and square. Do the same for the 2.25. After that, you want to put in a calculator (Desmos Graphing Calculator) √3²-2.25² adn get the answer for the line of C and D (-2.06). After that, you do the same but on the other side: Take the Hypotenuse of 4 and the -2.06 and form it into √4² -2.06². Your final answer would be...

x = 3.43
