The answer is C. plane j and plane QLM because you need to have at least three points to form a plane and also the letter J is on the diagram but it is not a point or a line.

Answer:

<h2>C. plane J and plane QLM</h2>

Step-by-step explanation:

Notice that the letter J is on the plane, but it's not a point on the plane, which means it represents the name of the plane.

So, plan J is a name.

We now by definition that we just need three points to graph a plane, that means we also need just three points to name a plane.

Therefore, a second name for this plane could be QLM or LMQ or MQL.

Therefore, the right answer is C., because it includes the right names for the given plane.

Find the value of x in the triangle shown below.<br> 13<br> 5<br> х

katen-ka-za [31]

Answer:

x=12

Step-by-step explanation:

This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that $C^2=a^2+b^2$ where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, $b=\sqrt{13^2-5^2}$ . Next, solve what is under the root to get, $b=\sqrt{144}$ . Finally, square root 144 for the final answer b=12.
