8.3 Ratios in Right Triangles To find trig ratios using right triangles To solve problems using trig ratios Background trigonometry- the word comes from 2 Greek words trigon-meaning triangle metron meaning measure. hypotenuse A B C Adjacent opposite A ratio of the lengths of sides of a right t...
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle. The basic trigonometric ratios are sin, cos, and tan, namely sine, cosine, and tangent ratios. The other important tr...

trigonometry [Gr.,=measurement of triangles], a specialized area of geometry concerned with the properties of and relations among the parts of a triangle. Spherical trigonometry is concerned with the study of triangles on the surface of a sphere rather than in the plane; it is of considerable ...
“trigon” means a triangle and the word ”metron” means a measure. Hence, trigonometry means the science of measuring triangles. In broader cases it is that branch of mathematics which deals with the measurement of the sides and the angles of a triangle and the problems allied with the ...
In the video, students are provided with a quick view of the supprt pole as well as a triangle with the angle of elevation and length of the adjacent side (the metre stick).Question Asked in Video:How Tall is the Support Pole?
is always the same (0.5) so in our triangle the opp (60) divided by the hyp (?) must equal the sin 30 0 so…. sin = opp/hyp sin 30 0 = 60/? Since the sin 30 0 is 0.5 lets change it to that 0.5 = 60/? Solve the equation. This equation may seem a little more difficult...

Ideally, a reference species (X) should represent the predominant emission from a single type of source and should not vary significantly due to local changes in photochemistry or other processes controlling air composition at the particular site to allow for urban-scale estimates. However, in a ...
