How do you find the measure of an angle in geometry?
take a protractor and line up the origin of the angle with the dot. then folow th line up to the corresponding numbe, which is the angle
What is the magnitude of an object if it is vector a is 5m and vector b is 3.5 m?
any length between 1.5 and 8.5 meters depending on the angle between the vectors. find the dot product of the two vectors to find the magnitude. e.g. two vectors a x b . y c z gives a.x+b.y+c.z= your final answer. The dots mean times by (btw)
Why is an angle measures 180 degrees?
A straight line. Draw a straight line. Make a dot/point on that line. From a point on the line to the left of the dot , sweep an arc to a point on the line to the right of the dot. You will find it to be 180 degrees.
How do you find the dot product ab of two vectors if you know their lengths and the angle between them?
<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.
How do you measure the size of angles?
Normally, you should be able to use a protractor ( a half circle shaped piece that has a lot of marks around the curved part.) Find the vertex of the angle (the spot two lines come together) On the flat pat of the protractor, there should be a dot in the middle. Put the vertex there. Now, line one of the lines up with the bottom of the angle, making sure you keep the dot on the vertex. Next, find the other line. follow it up to the curved part. There will be marks there that have numbers on them; find the one that matches up with your line. Those marks have marks, which are the degrees, or measures, of the angle. Now, you know the measure of your angle.
The angle between two vector force of magnitude?
The angle between two vector forces of magnitude can be calculated using the dot product formula: θ = cos^(-1)((A·B) / (|A||B|)) where A and B are the magnitudes of the forces. This formula gives the angle in radians.
What is formula of a works?
it is the dot product of displacement and force . i.e. Fdcos(A) where F is the magnitude of force , d is the magnitude of displacement and A is the angle between them

How to find the dot product of two vectors?
To find the dot product of two vectors, you multiply the corresponding components of the vectors and then add the results together. This gives you a single scalar value that represents the magnitude of the projection of one vector onto the other.
How do you find angle between vectors?
To find the angle between two vectors, you need to use this form: a ∙ b / (|ab|) = cos(θ) θ = arccos(a ∙ b / (|ab|)) where a and b are vectors. Compute the dot product and the norm of |a| and |b|. Then, compute the angle between the vectors.
How can you draw an angle of specified measure?
Use a protractor, or computer software such as GeoGebra (available for free).To draw an an angle of specified measure with a protractor:Draw a straight linePlace a dot at one end of the line. The dot represents the vertex of the angle.Place the center of the protractor at the vertex dot and the baseline of the protractor along line you drew (an arm of the angle).Find the required angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.
What is it when two vectors' dot product is one?
That fact alone doesn't tell you much about the original two vectors. It only says that (magnitude of vector-#1) times (magnitude of vector-#2) times (cosine of the angle between them) = 1. You still don't know the magnitude of either vector, or the angle between them.
Why is an angle measures 180 degrees?
A straight line. Draw a straight line. Make a dot/point on that line. From a point on the line to the left of the dot , sweep an arc to a point on the line to the right of the dot. You will find it to be 180 degrees.
When are vectors said to be perpendicular?
Perpendicular means that the angle between the two vectors is 90 degrees - a right angle. If you have the vectors as components, just take the dot product - if the dot product is zero, that means either that the vectors are perpendicular, or that one of the vectors has a magnitude of zero.
Where can you find a Dot Dot Curve CD?
You can find them at any store that sell's CD's for the most part.
How do you find the dot product ab of two vectors if you know their lengths and the angle between them?
<ab> = |a|*|b|*cos(x) where |a| is the length of the vector a, |b| is the length of the vector b, and x is the angle between them.
