Answer:
∠Z = 73°
∠Y = 101°
Explanation:
∠Z° and ∠107 are supplementary angles so their sum is equal to 180°.
∠Z + 107 = 180
- Subtract 107 from both sides.
∠Z = 73°
The sum of interior angles in the given rectangle is equal to 360°.
To find the value of y we need to add all measures.
y + 73 + 102 + 84 = 360
y + 259 = 360
- Subtract 259 from both sides.
y = 101
