Answer:
x = 64°
y = 18°
z = 98°
Notes:
- If 2 angles are directly across from each other, they have the same value, or same degree.
- A straight line equals 180°
Explanation:
Since x is directly across from 64°, x is also 64°
Since y is directly across from 18°, y is also 18°
Now, angles x, y, and z make a straight line. To find z, we have to add angles x and y, and then subtract from 180.
64 + 18 + z = 180
82 + z = 180
z = 98°
