Why will the horizontal and vertical components of a vector be equal in magnitude if the angle is 45 degrees?
Get some graph paper, draw two axes and bisect them with a 45 degree sloping line. Next pick any point on that 45 degree sloping line and from that point draw a line parallel to the horizontal axis so that it intersects the vertical axis. Do the same thing from the point drawing a line parallel with the vertical axis so that it intersects the horizontal axis. These two lines represent represent the components of your vector and if you measure them they will be of equal length and thus of equal magnitude. For ANY angle of slope (other than 45 degrees) the two vectors will not be of equal length.
What is a line that forms a right angle with the horizon?
The line that forms a 90 degree angle with any other line is called "perpendicular" or "orthogonal" to the other line.but u can call it right angled
If the base of an isosceles triangle is 74 what is the measure of the vertex angle?
You can't calculate any angle if all you know is one side of the triangle.
Why the slope of any vertical line is undefined?
Any vertical line is parallel to the y-axis in a co-ordinate plane.Therefore the angle of inclination is equal to 90 degrees.According to the formula , slope of a line = tanΘΘ = 90.Therefore slope = tan 90= sq.rt of {0/(4-4)}= sq.rt of 0/0= 0/0= undefined.
What type of angle is a 154 degree angle?
acute
