Video Solution

Step-by-Step Solution

Angle Y complements 180 and we can calculate it since we know the adjacent angle.

Let's calculate it as follows:

180105=75 180-105=75

Now that we found angle Y, we can calculate angle X since we have the other two angles in the same triangle: 72 and 75.

1807572=33 180-75-72=33

We can calculate angle Z since we have two angles in the triangle: 25 and 105

The sum of angles in a triangle is 180, so we'll calculate Z as follows:

18010525=50 180-105-25=50

Answer

x = 33, y = 75, z = 50
