Since each angle in a equilateral A is 60°. ? ?A = ?B = ?C = 60° Draw a perpendicular from A on side BC.

**find the value of sin 30 and sin 60 geometrically Math**

360 - 330 = 30, so we are subtracting 30 degrees from 360 to get the sin inverse, 330. Since we are subtracting from 360, the ratio will remain sin, and because it is in the 4th quadrant, the sin … how to find the slope length of a triangle Special Angles in Trigonometry. and the Calculation of Their Trig Ratios: Angles 0, 30°, 45°, 60°, and 90° are usual angles that people have a tendency to often use them in designs. For this reason, it is helpful to have the values of sine, cosine, tangent, and cotangent of these angles memorized for prompt use. You will find a very logical way to do this in the following.

- 2/06/1999 · To Dr. Math, Where do the values for sin 30, sin 60, etc. come from? We're told to memorize the values and take them for granted, but what is the actual derivation for getting the values? In other words, is there any way to prove that sin 30 = 1/2 or that sin 60 = sqrt(3)/2? Of course, I have the same question about cos, tan, etc, but if you explain sine I can figure those out. Thanks, Mike
