Which Side Lengths Form A Right Angle., Choose All That Apply, 5,12,13, 4,4,8, 2,3,4

Which side lengths form a right angle.

choose all that apply



5,12,13

4,4,8

2,3,4

 

Answer:

5,12,13

Step-by-step explanation:

5²+12²=c²

169=c²

Subtract c² from both sides.

169−c²=c²−c²

−c²+169=0

Subtract 169 from both sides.

−c²+169−169=0−169

−c²=−169

Divide both sides by -1.

c²=169

Take square root.

c=13

5²+12² = 13²

169=169

True

What Is A Tropical Storm?

What is a tropical storm?   A tropical storm is a spiral mass of strong and fast-moving winds that has a low-pressure center. It gains its energy from the convection that happens within it. The mass of clouds in a tropical storm can bring heavy rain and thunder. A tropical storm starts when a low-pressure area forms above the surface of the ocean. The low-pressure area is caused by the heat of the sun. This produces convection currents which swirl the mass of winds as the circulation between rising hot air and sinking cold air continues. This generates rotational energy until it continues to become a huge spiraling mass of winds. A tropical storm can be called by different names depending on where it is formed, namely tropical cyclone, typhoon , and hurricane . In the Philippines, it is called a typhoon. On the other hand, in the United States, it is called a hurricane . For more information about tropical storm, you may click the links below: brainly.ph/question/2140147 brainly....

Explain The 3 Laws Of Motion

Explain the 3 laws of motion   Law of Inertia > A body will remain at rest or move at a constant velocity unless acted upon by an external net or unbalanced force. Law of Acceleration > The acceleration of an object is directly proportional to the magnitude of the net force acting on it and is inversely proportional to its mass. Law of Interaction (Action-Reaction) > For every action, there is an equal and opposite reaction. This is what I memorized in my book so far, I hope this helps!
