Find the acute angle between the straight lines... - JAMB Mathematics 2009 Question
Find the acute angle between the straight lines y = x and y = \(\sqrt{3x}\)
A
15o
B
30o
C
45o
D
60o
correct option: b
x \(\leq\) 90o (acute angle)
x2 = 3x
3x = 90o
x = \(\frac{90^o}{3}\) = 30o
x2 = 3x
3x = 90o
x = \(\frac{90^o}{3}\) = 30o
