If sin theta = 4/5 and cos theta is in quadrant II, then cos theta and tan theta equal what?

larisa86 [58]

Using the pythagorean identity, $\cos^2{\theta} + \sin^2{\theta} = 1$ . Since $\theta$ is in quadrant ||, we know that $\cos{\theta}$ is negative. Solving the equation $\cos^2{\theta} + (\frac{4}{5})^2 = 1$ for $\cos{\theta}$ , we get that $\cos{\theta} = -\frac{3}{5}$ .

$\tan{\theta}$ is equal to $\frac{\sin{\theta}}{\cos{\theta}}$ , which is $-\frac{4}{3}$ .

*BEST ANSWER WILL BE MARKED BRAINLIEST*<br><br> MNOP is a square. what are the value of t and f?

igomit [66]

For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.

Therefore, we have the following equations:

$4t + 20 = 90\\7f + 6 = 90$

From these equations, we can clear the values of the unknowns.

For equation 1 we have:

$4t + 20 = 90\\4t = 90 - 20\\4t = 70$

$t = \frac{70}{4}\\t = 17.5$

For equation 2 we have:

$7f + 6 = 90\\7f = 90 - 6\\7f = 84$

$f = \frac{84}{7}\\f = 12$

Answer:

The values of t and f are given by:

$t = 17.5\\f = 12$
