If you work in engineering, you'll need trigonometry, and other advanced math topics, all the time. Otherwise, you can come along quite well without it, and will seldom find any practical use for it.
There are many formulas to find the area of a triangle although the most common is;A=1/2bh, where b=base and h=height
X2 + Y2 = The Hypoteneus2
There are several topics under the broad category of trigonometry. * Angle measurements * Properties of angles and circles * Basic trigonometric functions and their reciprocals and co-functions * Graphs of trigonometric functions * Trigonometric identities * Angle addition and subtraction formulas for trigonometric functions * Double and half angle formulas for trigonometric functions * Law of sines and law of cosines * Polar and polar imaginary coordinates.
Probably you should start by looking up the double-angle formulas, reducing the "4a" to some combination of "2a".
Greece introduced trignometry
=1/2=0.5
It is the shortened (slang) form of trignometry.
How tall is something that is too high to measure.
trignometry

Hey use triangulation method refer book of +1
one of them is called trignometry, one is a protractor and the other is a good question...

A landscape architect uses trignometry to measure the height of trees and buildings. They also measure slopes of hillsides.
