Assuming a right triangle (SohCahToa) sin(64) = 6.3/x x = 6.3/sin(64) x = 7.0 m

A wire from a post touches the ground at a point 6.3 meters from the post and if the the post and a wire form an angle of depression of 64 degrees so what is the length of the wire?
We need to use a little trigonometry to answere this. The sine of an angle in a right angled triangle is given by sine = opposite divided by hyponenuse that is the length of the side opposite the given angle divided by the length of the hypotenuse (or longest side). From that we can obtain that the length of the hypotenuse = opposite divided by sine. The sine is found by using a set of trigonometric tables or a scientific calculator (the majority of computers have a scientific calculator). The sine of 64 degrees is 0.89879, therefore the length of the wire (the hypotenuse) is 6.3 divided by 0.89879 which equals 7.009 metres.
What is tangent line?
tan A = (sin A) / (cos A) tan (A)= opposite side length/adjacent side length A is an angle measurement; amount of degrees or radians. If a line is tangent to a curve, it only touches the curve at one point. looks like )| but the line is touching the curve. In a circle, the tangent line touches the circle at one point and is perpinducular to the circle's radius if it is touching that same point.
How long is 180 degrees?
The question has little, if any, meaning. 180 degrees, as an angular measure, has no length. 180 degrees, as a measure of temperature, has no length. 180 degrees, as a series of qualifications in higher education has no intrinsic length.
Why does the internal date line only touch the north and south poles?
Touch what ? ! ? The International Dateline touches more than 400 miles of Antarctica, and the Pacific Ocean over most of its length. It also touches the meridian of 180° longitude over most of its length, and it touches the Earth's surface at every inch of its full and complete length of well over 12,000 miles.
What is the length of BC in this triangle angle BAC equals 40 degrees and angle ABC equals 50 degrees and angle BCA equals 90 degrees .?
In order to find length BC the length of AC or length of the hypotenuse must be given
What is a hypothesis for length of string telephone responding variable clairity of sound?
A hypothesis is a prediction or proposed explanation for something. A hypothesis for the length of string telephone with a clarity of sound responding variable can be about the string length affecting the quality of the sound.
What is the longest length of a triangle if its shortest length is 3.6cm when two of its angles are 37.25 degrees and 48.4 degrees?
Largest angle: 93.25 degrees Shortest angle: 37.25 degrees Shortest length: 3.6cm Longest length: 3.6*sin(94.35)/sin(37.25) = 5.93cm to two decimal places
Who to arc length Radius of the circle 4756 and angle 45deg find arc length?
(arc length)/circumference=(measure of central angle)/(360 degrees) (arc length)/(2pi*4756)=(45 degrees)/(360 degrees) (arc length)/(9512pi)=45/360 (arc length)=(9512pi)/8 (arc length)=1189pi, which is approximately 3735.3536651
Length of circle?
360 degrees
How do you find the arc ABC length 120 degrees 10?
An arc length of 120 degrees is 1/3 of the circumference of a circle

A ladder leans against a wall making an angle of 73 degress with the ground The ladder's base is 1.17m away from the wall Determine the length of the ladder?
Providing that the ground is level and that the wall is straight, you have the outline of a right angled triangle with an adjacent angle of 73 degrees and an adjacent length of 1.17 metres. In order to find the length of the hypotenuse (which is the ladder itself) we use the cosine ratio: cosine = adjacent/hypotenuse Which when rearranged is: hypotenuse = adjacent/cosine hypotenuse = 1.17/cosine73 degrees = 4.001755235 So the length of the ladder is 4 metres correct to one significant figure.
