The measure of the angles are Z = 90, X = 90, V = 90, Y = ∠20, W = ∠8 and W = ∠20
The sum of angles on a straight line is 180 degrees.
This means that:
Z + 90 = 180
X + 90 = 180
V + 90 = 180
Solve for the variables
Z = 90;
X = 90
V = 90
Also, alternate angles are equal.
This means that:
Y = ∠20
W = ∠8
This is so because the above angles are alternate angles.
Lastly, corresponding angles are equal.
So, we have:
W = ∠20
