Answer:
dis krap is too hard
Explanation:
cos x = a·b / |a|·|b|
|a| = √3² + 5² = √9 + 25 = √34 = 2√17
|b| = √2² + 6² = √4 + 36 = √40 = 2√10
a.b = 3*5 + 2*6 = 15 + 12 = 27
a.b / |a|.|b| = 27 / 2√17 * 2√10 = 27 / 4√170 = 27 / 4 * ~13,03
a.b / |a|.|b| = 27 / ~52,15 = ~0,51
x = [tex]cos^{-1}[/tex](0,51)
x = ~59.33º =~60º???
