Triangle COA is an isosceles triangle since duration of CO duration of AO rádius 14 cm. California 2 CO 2 AO 2 - 2 CO AO cos (angle COA) Substitute CA, CO and AO by their numerical beliefs and convey cos(angle COA) as follows cos(position COA) 14 2 14 2 - 12 2 2 14 14 31 49 Size of position COA is usually given by. Angle COA arcos(31 49) Based to the théorem above, the size of position CBA is usually equivalent to half the size of angle COA. Angle CBA (1 2) arcos(31 49) 25.38 degrees (approximated to 2 decimal places) Even more Recommendations and Hyperlinks to Geometry Geometry Lessons, Issues and Interactive Applets.
