<prompt> Bala ka hare angle ea kgutlotharo ha tse tharo tsa mahlakore a eona a 8 cm, 3 cm, le 7 cm,.nan  <response>: Instruction in English: Calculate the interior angle of a triangle when three of its sides are 8 cm, 3 cm, and 7 cm. . Response in English: To calculate an interior angle of a triangle when the lengths of its sides are given, we can use the cosine rule, which states that for any triangle ABC with side lengths a, b, and c, the cosine of angle C is given by:cosC a2 b2 - c2 2abLets say we want to find the measure of angle C opposite to the side with length c 8 cm. We can plug in the values of the sides of the triangle into the formula above:cosC 32 72 - 82 2 3 7 -11 42Now we take the inverse cosine of both sides to solve for C:C acos-1142 108.23 degreesSo, the measure of the interior angle opposite to the side with length 8 cm is approximately 108.23 degrees. . Response in Sesotho: Ho bala karolo e ka hare ea khutlo-tharo ha bolelele ba mahlakore a eona bo fanoa, re ka sebelisa molao oa cosine, o bolelang hore bakeng sa kgutlotharo efe kapa efe ABC e nang le bolelele ba mahlakore a, b, le c, cosine ea angle C e fanoa ke: cosC a2 b2 - c2 2ab A re re re batla ho fumana tekanyo ya angle C e bapaneng le lehlakore le bolelele ba c 8 cm. Re ka hokela boleng ba mahlakore a kgutlotharo foromong e ka hodimo: cosC 32 72 - 82 2 3 7 -11 42 Joale re nka cosine e fapaneng ea mahlakore ka bobeli ho rarolla bakeng sa C: C acos-1142 likhato tse 108.23 Kahoo, tekanyo ea angle e ka hare e mabapa le lehlakore le bolelele ba 8 cm ke likhato tse ka bang 108.23.
