Answer:
<h3><em>
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).</em></h3>

Answer:
sum of angles in atriangle=180°
Step-by-step explanation:
w-45°+w-37°+w+19°=180°(sum of angles in a triangle)
3w=180°+45°+37°-19°
3w=243°
w=81°
You can write 5 to the negative fourth power as 5^(-4). In cases, when you have negative power, you just have to put 5^4 in the denominator. So, instead of 5^(-4), you have 1/(5^4).
5^4 equals to 625.
In the last step you have to divide 1 by 625.
The result is 0.0016.
Z=13 I had a similar problem before and I've gotten it right.
