How do you work out angles with only numbers. for example im trying to make a 30 degree angle with only a straight ruler is it possible for me to work a height and apply the angle?

For certain angles, the answer is yes. For 30o to the horizontal (in the positive x direction), you need to measure the horizontal distance to be twice the vertical distance. For example, draw a triangle with a base length of 10cm and, at a right angle to the base, measure a height of 5cm. The angle to the horizontal (the smaller angle) will be 30o. (The opposite is true for the angle of 60o).

How numbers got their shape?
The Arabic numbers, which is what are numbers are based on for the English language and are very similar to, use to have no curves or curved angles in them and had all acute, obtuse, or right angles. According to what number it was (for example 3) had three angles. Another example is 4, which still has four angles today.
What are ways you use straight angles in real life?
You can use straight angles to make sure countertops, or walls are straight and in a right formation.
Two angles that form a straight line?
Supplementary angles.
What do the all the angles on a straight line add up to?
All The Angles On A Straight Line Add Up To 180 Degrees.
What is a straight angles degrees?
If you mean a straight line, then 180 degrees.
How many right angles can you fit into a straight angle?
Infinite numbers of angles * * * * * Without overlapping, 2.
How were numbers named?
Numbers were named after the number of angles they represented, and each angle represented a quantity. For example, the number one has one angle, number two two and so on. They have to be written with straight lines (not curved).

Is it possible to draw a reflex angle so the other angles arms are acute obtuse straight?
Acute or obtuse: Yes. Straight: No.
Is it possible to bisect the angles in a rectangle?
Any angle can be bisected using a compass and a straight edge.
Is how are straight angles different from right angles a statement?
"How are straight angles different from right angles?" Is this a statement?
When was No Straight Angles created?
No Straight Angles was created in 1994.
How are all numbers created?
Notice the number of angles when you write/display the numbers (1-9) with straight lines. For example: Two (2) has two angles when written/displayed as (Z). Three (3) has three angles when written like the Greek letter "Sigma". Six (6) has six angles and Eight (8) has eight angles (please see the display in digital watches or calculators) Only Zero (0) is circular- or ellipse- shaped which has no angle.
Are two straight angles supplementary?
No. Supplementary angles are angles that add up to 180˚. One straight angle already equals 180˚. Two straight angles add up to 360˚.
What does the interior angles of a convex polygon add up to?
The sum of the interior angles of a convex n-gon is (n-2) straight angles or in degrees (n-2) times 180. Example ; hexagon n= 6, n-2 is 4 , so the total is 4 straight angles of 720 degrees.
An angle measure 180 is called?
Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.
What is a word that has 5 acute 2 obtuse and 5 right angles?
It is possible that this the question concerns upper case letters in the Roman alphabet, and excludes angle between a straight line and a curve (the curved part of P meets the vertical straight at right angles). In that case, one possible answer is WAFT.
