Straight : A straight angle is .
Right: A right angle is .
Since the angle is more than but less than . So, it is an obtuse angle.
Answer: 0.002 inches
Step-by-step explanation:
A stack of 500 pieces of paper is 1.015 inches tall. The appropriate estimate for the thickness of each piece of paper would be gotten by dividing 1.015 by 500. This will be:
= 1.015 / 500
= 0.00203
= 0.002 inches
So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct
