# 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 = $$\sqrt{3x}$$

A) 15o

B) 30o

C) 45o

D) 60o

### Explanation:

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

## Dicussion (1)

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