Two equals Sides. One Angle. In a CIRCLE.Hi, To obtain the area of a a triangle inside a circle with radius 12. and angle pi/3 ( 60deg). A= 1/2 *b*h . = 1/2*12* h h= tan(30deg)*12 = this is correct> we can intersect pi/3 and use tan to equate the height? Zen. |

I just imagine a right triangle with angles 30°, 60° and 90°. cos(30°) = ?3/2 = h/12 i.e. h = 6?3. ? ½ x 12 x 6?3 = 6²?3 = 36?3. |
