Vertical angles are equal to each other, so to solve this, you can set the angle measures equal to each other and solve for x.
Z = Y Replace X and Y with their values
4x - 17 = 2x + 7 Isolate the value. Start by adding 17 to both sides
4x = 2x + 24 Subtract 2x from both sides
2x = 24 Divide both sides by 2
x = 12

Answer:
f(x) = -5/3x + 5/3
Step-by-step explanation:
if x = 4 ; f(x) = -5
if x = -2 ; f(x) = 5
f(x) = ax + b
-5 = 4a + b <em>(</em><em>1</em><em>)</em><em> </em>
and
5 = -2a + b <em>(</em><em>2</em><em>)</em>
<em>(</em><em>1</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em>
2a + 2b = 0
a = -b
<em>(</em><em>1</em><em>)</em><em> </em>-5 = 4a - a
-5 = 3a
a = -5/3

f(x) = -5/3x + 5/3
