<h3>Answer: 
</h3>
Explanation:
The identity we'll use is cos(-x) = cos(x) for any value of x.
So cos(-150) = cos(150).
Then locate the angle 150 on the unit circle. The terminal point is
The x coordinate of this terminal point is the value of cos(150).
Answer:
1.93433
Step-by-step explanation:
Since all triangles have an interior angle sum of 180, the second angle is 45. this also means that x and y are equal. Using the pythagorean theorem, we can produce the equation . dividing both sides by two we get
. when we take the square root of root 14 we get 1.934335
