Answer:

14/11

Step-by-step explanation:

Put the 3 into the one half by multiplying the 3 by the denominator. So now you have -7/2.

Then, make a common denomitator of 4, so you multiply top and bottom of fraction by 2 to get -14/4

Then, divide both sides of the equation by -11/4, and to do this, just multiply by the reciprocal of -4/11

-14/4 x -4/11 = 56/44

Simplify and get 14/11

Trig///HELPP PLEASE!! i’ve been stuck on this for 30 minutes!!
ddd [48]

Answer: There are two solutions and they are

theta = 135

theta = 225

=============================================================

Explanation:

Recall that x = cos(theta). Since the given cosine value is negative, this indicates x < 0. Theta is somewhere to the left of the y axis, placing it in quadrant 2 or quadrant 3.

It turns out there are two solutions, with one solution per quadrant mentioned above. Use the unit circle to find that the two solutions are:

theta = 135

theta = 225

You're looking for points on the unit circle that have x coordinate equal to x = -sqrt(2)/2. Those two points correspond to the angles of 135 and 225, which are in quadrants 2 and 3 respectively.

--------

I recommend using your calculator to note that

-sqrt(2)/2 = -0.70710678

cos(135) = -0.70710678

cos(225) = -0.70710678

The decimal values are approximate. Make sure your calculator is in degree mode. Because those three results are the same decimal approximation, this indicates that cos(135) = cos(225) = -sqrt(2)/2.
