Directional 2595

Calculate the interior angles of triangle ABC using vectors. Coordinates A [2; 4] B [4; 6] C [0; -4]. Calculate directional vectors of sides, parametric and general equations of sides, parametric and general equations of lines, calculate area, calculate height.

Correct answer:

A =  149.03 °
B =  23.198 °
C =  7.7658 °

Step-by-step explanation:

AB=(42,64)=(2,2) BC=(04,46)=(4,10) CA=(20,4(4))=(2,8)  s(AB)=arctan(2/2)=45° s(BC)=arctan(10/(4))=68.198° s(CA)=arctan(8/2)=75.96375°  A=α=(180s(CA))+s(AB)=149.03°
