Finding an Angle in a Right Angled Triangle - Math is Fun. Mathsisfun.com On your calculator, try using sin and sin-1 to see what results you get!.... The angle ? as defined above can go from 0 to 360°, but (sin ?, cos ?) are only defined for 0 to 90°, covering only the part of the plane where both x and y are positive. When one or both are negative , the angle ? is larger than 90 degrees, and such angles never appears in any right-angled triangle.

27/06/2003 · / /___._____/ b Here, we know that the sine of the angle is sqrt(3)/2, so we know that a sqrt(3) - = ----- c 2 which means that if we know the length of side c, we can use that and the angle to find the height of the parallelogram. We could do something similar starting from a scalene triangle: . .| . c . . .a . . . . . . . . . b So one way to answer your question is to say that you use... 2.

2. Sin, Cos and Tan of Sum and Difference of Two Angles. by M. Bourne. The sine of the sum and difference of two angles is as follows:... There is no angle whose sine is 2, because the hypotenuse is always the largest side of a right-angled triangle, and hence the maximum value the sine of an angle can be is 1. In part (1) of the activity above, you used your calculator to find an angle whose sine is 0.5.
