Step-by-step explanation:

x^2 + y^2 = r^2 --> r =\sqrt{(-4)^2 + 5^2} =\sqrt{41}

cos = x /r = -4 /\sqrt{41}

sin = y /r = 5/\sqrt{41}

tan = sin /cos = -5 /4

What is the square root of 4/225
LuckyWell [14K]
2 / 15

This is simpler than you think. Just take the square root of the denominator and of the numerator and stick it back into fraction form. The square root of 4 is 2 and the square root of 225 is 15. Voila: 2 / 15.
