Find the acute angle between the straight lines y = x and y = \(\sqrt{3x}\)


Question

Find the acute angle between the straight lines y = x and y = \(\sqrt{3x}\)

Options

A) 15o

B) 30o

C) 45o

D) 60o

The correct answer is B.

Explanation:

x \(\leq\) 90o (acute angle)
x2 = 3x
3x = 90o
x = \(\frac{90^o}{3}\) = 30o
