Is 83 over 2 a rational number

Mathematics
1 answer:
Deffense [45]4 years ago
6 0

Answer:

Yes, it is a rational number

Step-by-step explanation:

If you divide 83 over 2, you will get 41.5.

Since you can turn that into a fraction, it is considered a rational number.

However, if it's something like this 1.34246928... Then it's not rational since it's random numbers repeating over and over, there's no real pattern.

The smallest angle of a right triangle is 20-degree angle. What is the measure of the medium angle?
Veronika [31]

Answer:

70 degrees.

Step-by-step explanation:

Hello!

It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.

90 + 20 = 110

180 - 110 = 70.

So the medium angle is 70°.

Hope this helps!

If angle 1 and angle 5 are vertical angles and angle 1 equals 55, then angle 5 will equal ______.
Ainat [17]
Hey there, and good morning to you! :D

Vertical Angles are angles that are congruent and have the same measure, and they usually form a straight line through the vertex. (if you were to draw through them) They actually share the same vertex.

So if angle 1 and angle 5 are vertical angles, and angle 1 equals 55 degrees,

then angle 5 will equal 55 degrees. 

I hope this helps!
