0.4 is rational.
Any irrational added to a rational is irrational.
Therefore we only need to add ANY irrational to 0.4 to produce an irrational number.
Examples of irrational numbers are: pi, e, sqrt(2), sin(pi/3), tan30 degrees, etc.
complementary angles are angles whose measures equals 90° when added. so to find the measure of this angle, we subtract 25° from 90°. the measure of the angle is 65°.
Answer:
1
Step-by-step explanation:
2+2=4
4-3=1
The correct answer is it is a figure with at least 3 straight sides. When you think of a square or a triangle they both have at least 3 sides that are straight. A circle doesn't have any straight sides so it is not a polygon.
You can prove that the other answer is wrong because of two things:
The definition of a polygon is a plane figure with at least three straight sides.
Also, when you think of most shapes what do they all have in common? The have at least three straight sides
