Answer:
b = 2
Step-by-step explanation:
Original Equation:
-12 + 3b - 1 = -5 - b
Add b to both sides
-12 + 4b - 1 = -5
Add 12 to both sides
4b - 1 = 7
Add 1 to both sides
4b = 8
Divide both sides by 4
b = 2
Hope this is what you need :)
Answer:
11/12
Step-by-step explanation:
Using a trigonometric identity, it is found that the values of the cosine and the tangent of the angle are given by:
<h3>What is the trigonometric identity using in this problem?</h3>
The identity that relates the sine squared and the cosine squared of the angle, as follows:

In this problem, we have that the sine is given by:

Hence, applying the identity, the cosine is given as follows:






The tangent is given by the sine divided by the cosine, hence:
