ANSWER

$\cos(150 \degree) = - \frac{ \sqrt{3} }{2}$

√m/3=4 My teacher didn't explain how to solve these to well can someone explain?

Andrews [41]

√m/3 = 4

To remove the radical sign, square both sides.

(√m/3)² = 4²
m/3 = 16

To remove the denominator of 3, multiply both sides by 3.
3 (m/3) = 3(16)
m = 48

To check: Substitute m by its value.
√m/3 = 4
√48/3 = 4
√16 = 4
4 = 4
