(PLEASE ANSWER!) Two distinct lines, L and M, are each perpendicular to the same line N. What is the measure of the angle where line L meets line N? What is the measure of the angle where line M meets line N?

Answers

Answer:

90 and 90

Step-by-step explanation:

If they are perpendicular it means they cross at a 90 degree angle so since both L and M are perpendicular to N both the answers would be 90

Hope This Helps :)

The measure of the angle where line L meets line N is 90° ;

and the measure of the angle where line M meets line N is 90°.

What are perpendicular lines?

In geometry, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

Now it is given that,

Two distinct lines, L and M, are each perpendicular to the same line N.

Line L is perpendicular to line N.

Since angle between two perpendicular lines = 90°.

So, angle between line L and line N = 90°

Similarly, Line M is also perpendicular to line N.

Therefore, angle between line M and line N = 90°

Thus, The measure of the angle where line L meets line N is 90° ;

and the measure of the angle where line M meets line N is 90°.
