given that sin theta= 1/4, 0 is less than theta but less than pi/2, what is the exact value of cos theta
lapo4ka [179]

Answer:

\cos{\theta} = \frac{\sqrt{15}}{4}

Step-by-step explanation:

For any angle \theta, we have that:

(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1

Quadrant:

0 \leq \theta \leq \frac{\pi}{2} means that \theta is in the first quadrant. This means that both the sine and the cosine have positive values.

Find the cosine:

(\sin{\theta})^{2} + (\cos{\theta})^{2} = 1

(\frac{1}{4})^{2} + (\cos{\theta})^{2} = 1

\frac{1}{16} + (\cos{\theta})^{2} = 1

(\cos{\theta})^{2} = 1 - \frac{1}{16}

(\cos{\theta})^{2} = \frac{16-1}{16}

(\cos{\theta})^{2} = \frac{15}{16}

\cos{\theta} = \pm \sqrt{\frac{15}{16}}

Since the angle is in the first quadrant, the cosine is positive.

\cos{\theta} = \frac{\sqrt{15}}{4}

PLEASE HELP! FIRST AND BEST ANSWER WILL BE MARKED BRAINLIST!!<br> second sections
Vika [28.1K]

Answer:

Well, for one thing I can't read the image--it's too small!

But I know these problems well. If I am correct, this is a spinner probability problem.

Your spinner appears to have 5 sectors, all equal in area, therefore making their probability equal.

So each of those has a prob of 1/5 in the scheme of things.

To find the combonational probability below, multiply the prob of each outcome together to find each.

Have a great day, and feel free to comment with questions!
