## Plane trigonometry

2020-8-17Other articles where Plane trigonometry is discussed: trigonometry: Plane trigonometry: In many applications of trigonometry the essential problem is the solution of triangles If enough sides and angles are known the remaining sides and angles as well as the area can be calculated and the triangle is then said to be solved Triangles can

2 By Yang Kuang Elleyne Kase To put angles on the coordinate plane essentially all you do is look at the trig ratios in terms of x and y values rather than opposite adjacent and hypotenuse Redefining these ratios to fit the coordinate plane (sometimes called the point-in-the-plane definition) makes visualizing these easier Some of the angles for instance are larger than 180 degrees

2018-12-14A truss for the roof of a house is constructed from two identical right triangles Each has a base of 12 feet and height of 4 feet Find the measure of the acute angle adjacent to the 4-foot side (6 3#57) The line (y = frac{3}{5} x) passes through the origin in the x y-plane What is the measure of the angle that the line makes with the

Explanation: In the figure above angle ADB is a right angle Because side AC is a straight line angle CDB must also be a right angle Let's examine triangle ADB The sum of the measures of the three angles must be 180 degrees and we know that angle ADB must be 90 degrees since it is a right angle We can now set up the following equation
