What is the angle made by two parallel lines.Is it 0 or 180.If it is both when should each be considered?

Angles are formed when two lines intersect (depends on the way the lines intersect to determine what kind of angles they are). Since parallel lines do not intersect each other at all, there is no angle between them.

All triangles have at least 2 acute angles?
True. The reasoning behind it is this: the sum of the angles in any triangle will always equal 180o.Equilateral (all sides & angles equal)3x = 180x = 60Isosceles (two equal sides & angles) - can include Right triangle (90 + 45 + 45)x + 2y = 180y = (180-x)/2No matter what x equals (acute, right, or obtuse), y will be less than 90 (acute) because half of 180 is 90 and half of anything less than 180 will be less than 90.Scalene (all sides & angles different) - can include Right triangle (90 + x + y)x + y + z = 180If one angle is obtuse...x > 90180 - x < 90y + z < 90If together they are less than 90, then clearly both are less than 90 (acute)
Why is it not possible to draw a right equilateral triangle or an obtuse equilateral triangle?
It's not possible at all to contain a right or obtuse angle in an equilateral triangle.Here's the facts:a triangle measures 180 degreesall the sides must add up to 180if it doesn't, you don't have a triangleit is 3 sidedan acute angle can be ranging from 1-90 degreesa right angle can only be 90 degreesan obtuse angle has anywhere from 91-179 degreesa straight angle is 180 degrees and is also called a line. Combining those lines forms angles, which forms figures, so you can't get away with thatThere's 3 sides to a triangle, right? Yes/NoIf there's 3 angles, then there's got to be 3 sides, am I right? Yes/NoAnd there's 180 degrees in a triangle, correct? Yes/NoIf you answered "Yes" to any of these questions, give yourself a pat on the back. Now think about this one:3x=180The coefficient stands for the number of angles in a triangle (keep in mind that this equation's for equilateral/equiangular triangles only!). Now solve it.3x=1803x= 1803orx= 60 (acute angle)
If three hens lay four eggs in five days how many days will it take eight hens to lay a dozen eggs?
5 days i thinkAnswerIf three hens lay four eggs in five days then one hen lays 4/15 eggs in one day.how many days for one hen to lay 48 eggs?4/15 x = 48x=180If twelve hens are on the job?180/12 = 15 days
What is the formula for finding the distance around a circle?
Finding the distance around a circle is simple. The distance around a circle is called the circumference. To find the circumference, you must do the following: Diameter x pi. It can also be written as 2 x pi(3.14) x Radius.The distance around a circle is called the circumference. To find the circumference, you multiply Pi by diameter. Another way to find it is 2 times 3.14 times radius. 2x3.1.4xr.The distance around a circle---it's circumference---or the length of some portion thereof---a segment---is measured in linear distance units such as inches, centimeters, feet, or meters.The portion of a circle (the relative distance around) that a segment represents---the segment's circular arc---is measured in units of angular magnitude. In basic geometry and lay usage, the most common angular unit is the degree. In scientific and higher math usage, the most common unit is the radian. The circumference of a circle has an arc of 360° (360 degrees), or 2π rad (2 × pi radians). A radian therefore is equivalent to 180/π degrees. Other units of angular magnitude include the turn (360° or 2π rad), grad (aka gon; 1/400 turn), quadrant (1/4 turn), arcminute (1/60°), and arcsecond (1/60 arcminute).The length of a segment---the distance along it---can be determined according to any of the following formulas, where:L represents the length of the segment,θ the circular arc in radians,⍺ the circular arc in degrees,r the radius of the circle,C the circumference of the circle;If you know the radius and need the total circumference:C = 2 × π × rIf you know the radius and arc, and need the segment length, one of:L = θ × rL = (⍺ × π × r) / 180If you know the circumference and arc, and need the segment length, one of:L = (θ × C) / (2 × π)L = (⍺ / 360) × CThe circular arc of a segment can be determined according to any of these formulas;If you know the radius and length, one of:θ = L / r⍺ = (180 × L) / (π × r)If you know the circumference and length, one of:θ = (2 × π × L) / C⍺ = (360 × L) / CThe circumference of (distance around a) circle is equal to the diameter times pi. It is also equal to 2 x pi x radius.
What were the laws in sumer?
The laws in Sumer were set down in the Code of Ur-Nammu, one of the earliest known legal codes. These laws covered various aspects of society including marriage, inheritance, property rights, and crimes such as theft and murder. They were inscribed on clay tablets and served as a guide for justice and governance in ancient Sumer.
