    Is there a formula to determine force based off mass, distance and angle?

    I am currently studying forces in Physics, and the professor basically just gave the definition of tension force, and the book isn't helping me with a problem that appears to be using tension force. Basically, the problem involves a rope strung across a 10 meter gap between two buildings. The...

    Finding a 3D vector at a given angle between two other 3D vectors

    Hello, Say I have two 3D vectors: v1 and v2 My known variables are the coordinates of each vector from the origin: (v1x , v1y , v1z) and (v2x , v2y , v2z​) , and in turn, the magnitude of each vector: v1m and v2m I know that I can find the angle between these two vectors with the equation...

    Help with Central Angle and Inscribed Angles

    Hello all. I am refreshing my geometry skills. I have a problem that states: Find the value of x. I know that the central angle is equal to the length of the arc. I think what I have here is an inscribed angle but I do not know the value of the intercepted arc. I am lost. Please give me a hint...

    Coterminal Angle

    A) Find an angle between 0 and 2π that is coterminal with -19π/10 B) Find an angle between 0° and 360° that is coterminal with 810°. Need a little help. I am understanding on the concept, but just not quite there yet. It'd be awesome if you guys can work out both of these.

    Find the angle on the left

    I have two lines I need to calculate the angel between these lines. using the following formula I can calculate the acute angle. however I sometimes I want the obtuse angle 180- the above equation will get me that. The angle I want is always on the right sometimes its the acute one some times...

    Angle Bisectors of Triangle ABC

    Question: The angle bisectors of Triangle ABC meet at Point I, AB:BC:CA=4:5:8, and the area of Triangle ABC is 68. What is the area of Triangle BCI? No diagrams were provided. We are supposed to draw our own. Btw, Triangle BCI is created with the lines of the bisectors, I'm pretty sure :)

    In triangle, 1 angle is twice as big as 1 angle and 3/4 the size of the other. Help!

    In a triangle (180 degrees), one angle is twice as big as one angle and 3/4 the size of the other. What is the measure of the smallest angle? How would you solve this? I have tried working backwards (as in, from the answers) but to no avail. There are too many variables? Choices: 48 96 98 72...
