Answer:
x = 44
y = 136
z = 136
Step-by-step explanation:
The angles of a triangle have to add up to 180°
54 + 82 + x = 180
136 + x = 180
x = 44
We know that y and z are vertical angles, so they have the same measurements.
Also, x and the other angle across from it are also vertical angles.
88 + 2n = 360
2n = 272
n = 136
Therefore,
x = 44
y = 136
z = 136

Step-by-step explanation:
Given
Solving (a): Expression for V(x)
We have:
Substitute known values
Solving (b): Simplify V(x)
We have:
Solve the expression in bracket
Factor out x
Express as difference of two squares
Cancel out x - 3
Solving (c): V(50), V(100), V(1000)
Substitute 50 for x
Substitute 100 for x
Substitute 1000 for x
Solving (d): V(x) = 3000, find x
Cross multiply
Equate to 0
