All circles are similar with scale factor R/r where R and r are the radius of the larger and smaller circle respectively. the scale factor here is 6/3 = 2 Upvote • 0 Downvote Properties of a 30-60-90 Right Triangle A special kind of triangle. A 30-60-90 right triangle (literally pronounced "thirty sixty ninety") is a special type of right triangle where the three angles measure 30 degrees, 60 degrees, and 90 degrees. The triangle is significant because the sides exist in an easy-to-remember ratio: 1:\(\sqrt{3}\):2.
the other. Obviously, the sides of two similar right triangles are different due to the net difference in the size between the triangles. However, their corresponding angles and trigonometric ratios are the same. In what follows, we use the similar right triangles in Figure 7 to illustrate these facts. Figure 7.
Answer. For any problem involving a 30°-60°-90° triangle, the student should not use a table. The student should sketch the triangle and place the ratio numbers. Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. Example 2. Evaluate sin 30°. Answer.
