Can you have decimals in coordinates?
Decimal degrees (DD) express latitude and longitude geographic coordinates as decimal fractions and are used in many Geographic Information Systems (GIS), web mapping applications such as Google Maps, and GPS devices. Decimal degrees are an alternative to using degrees, minutes, and seconds (DMS).

Why are coordinates in minutes and seconds?
Degrees, Minutes, Seconds (DMS) Degrees for DMS are divided into 60 minutes and then each minute is divided into 60 seconds. This is just like the hours on our clocks and goes back to the Babylonians who worked with a base 60 number system!

- Then draw two arcs of same radius from the point where you drew 90°
- Now using those arcs draw two more arcs such that they intersect at some point.
How do you draw a 127 degree angle with a compass?

- By same measure from point , draw an arc which cuts before arc at.
How do you convert degrees and minutes to decimal?
Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600)
- First, convert minutes and seconds to their degree equivalents and add the results. 25’/60 = 0.4167° 30″/3600 = .0083°
- Then, add this number to the number of degrees. 39° + 0.425° = 39.425°
- So, the final result is: 39° 25′ 30″ = 39.425°
How do you justify a 45 degree angle?
6=)Join OE ,then angle AOE ==90°. 7))Draw the bisector OF of Angle AOE ,then Angle AOF =45°….
- Draw a ray OA .
- With O as centre and any suitable radius draw an arc cutting OA at B .
- With B as centre and same radius cut the previous drawn. arc at C and then with C as centre and radius cut the arc at D.
Can an angle be a decimal?
An angle could have a measurement of 35.75 degrees. Notice that here we are expressing the measurement as a decimal number. Using decimal numbers like this one can express angles to any precision – to hundredths of a degree, to thousandths of a degree, and so on.
What are the 7 types of angles?
The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.
How do you measure 45 degrees?

How do you convert trigonometry to decimal degrees?
- To convert decimal degree to degree, minutes, and seconds, the whole units of degrees will remain the same. Multiply the decimal by 60 .
- Multiply 0.568 by 60 . 34.08.
- Take the remaining decimal and multiply by 60 and take the whole number portion to find the seconds. 0.08⋅60.

How do you find an angle using trigonometry?
- Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
- Step 2 SOHCAHTOA tells us we must use Cosine.
- Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
- Step 4 Find the angle from your calculator using cos-1 of 0.8333:
How do you construct a 147 degree angle?
- draw a line OA.
- using protractor and center ‘o’ draw an angle AOB =147°.
- Now taking ‘o’ as center and any radius draw a arc that intersects ‘OA’ and ‘OB’ at p and q.
- now take p and q as centers and radius more than half of PQ, draw arcs.
- both the arcs intersect at ‘R’
- join ‘OR’ and produce it.
How do I find the degree of an angle?
For example, if you know that 4 of the angles in a pentagon measure 80, 100, 120, and 140 degrees, add the numbers together to get a sum of 440. Then, subtract this sum from the total angle measure for a pentagon, which is 540 degrees: 540 – 440 = 100 degrees. So, the missing angle is 100 degrees.
What is the degree of tan?

How do you convert COS to degrees?
You can convert radians into degrees by multiplying it with 180/Math. PI , Furthermore the inverse cosine (or cos^-1 like some textbooks denote this) is the Math. acos method ( a standing for arc ). double AB = 125; double AC = 150; double angleA = Math.
What is an angle of 45 degrees?
A straight angle measures 180°. An angle can be measured using a protractor, and the angle of measure 90 degrees is called a right angle. In a right angle, the two arms are perpendicular to each other. When the right angle is divided into two equal parts each angle measures 45°.
