The terminal side of 0 is in quadrant II and cos 0 = -5/13. What is sin 0?
zaharov [31]

Answer:

\displaystyle \sin\theta=\frac{12}{13}

Step-by-step explanation:

We are given that:

\displaystyle \cos\theta =-\frac{5}{13}\text{ where $\theta$ is in QII}

Recall that cosine is the ratio of the adjacent side to the hypotenuse. Using the Pythagorean Theorem, solve for the opposite side (we can ignore the negative for now):

o=\sqrt{13^2-5^2}=12

And since θ is in QII, sine is positive, and cosine and tangent are both negative.

Sine is the ratio of the opposite side to the hypotenuse. Therefore:

\displaystyle \sin\theta=\frac{12}{13}

Can someone help me?
Readme [11.4K]

Answer:

B

Step-by-step explanation:

The answer is B because if you move two times to the right it gives you 0.09 like the eqution.

But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.

Just reminder: B and D have the same result!! just different coefficient
