Answer:
The answer to the problem is -15.52
This is a 45-45-90 triangle or a right triangle created by the sides.
Because of this being a right triangle and 45 degrees being given already for one angle you would add 90 and 45 which will give you 135. You would subtract 135 from 180 because all the angles of a triangle add up to 180°. 180-135=45. X=45°
Answer:
Sin(t) =
and 
Step-by-step explanation:
The secant function is the reciprocal function of the cosine function. Therefore, given that
then, if
then
.
On the other hand, if cos (t) = 1/2 ⇒ t = ±
Then, the sin(
) = 
Answer:
The correct answer is A

Step-by-step explanation:
We want to determine the decimal equivalence of
.
We perform the long division as shown in the attachment.
Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is
, will be inside the long division sign.
We see that the quotient of our long division is
.
We can rewrite this as 
Therefore
.
