Answer: The answer is 4.
Step-by-step explanation:
Distribute 3/4 with the (x+8). You will get 3/4x and 24/4, which is 6. Your equation will look like this: 3/4x +6=9. Subtract 6 to 9 to get 3. It will now be 3/4x = 3. Now divide 3/4 on both sides, and the answer will be x=4.

Trigonometric Identities.
To solve this problem, we need to keep in mind the following:
* The tangent function is negative in the quadrant II
* The cosine (and therefore the secant) function is negative in the quadrant II
* The tangent and the secant of any angle are related by the equation:
We are given:
And θ lies in the quadrant Ii.
Substituting in the identity:
Taking the square root and writing the negative sign for the secant:
