Answer:
65
Step-by-step explanation:
They are vertical angles; so angles are congruent
*<em>Vertical angles are always congruent*</em>
<em>Congruent means equal or same.</em>
1) Since they are congruent, you form an equation.
<h2>
145 = 2x + 15</h2>
2) Solve by subtracting 15 from both sides. 
<h2>
145 = 2x + 15</h2><h2>
- 15            -15</h2><h2>
----------------------</h2><h2>
130 = 2x</h2>
3) Solve by dividing 2 from both sides
<h2>
130/2 = 2x/2</h2>
4) Simplify
x = 65

Answer:
   (√7)/3
Step-by-step explanation:
The relationship between tangent and cosine is ...
   tan(α) = √(1/cos(α)² -1)
The cosine of the angle is given as 3/4, so the tangent is ...
   tan(arccos(3/4)) = √(1/(3/4)² -1) = √(16/9 -1) = √(7/9)
   tan(arccos(3/4)) = (√7)/3
