Answer:
We know that in a parallelogram two opposite angles are equal -
<u>Given</u><u> </u><u>-</u><u> </u>
- angle x is equal to the two - third of it's adjacent angle y.
Now, by using equation (1) :
<u>Now</u><u>,</u><u> </u><u> </u><u>by</u><u> </u><u>putting</u><u> </u><u>the</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>k</u><u> </u><u>in</u><u> </u><u>x</u><u> </u><u>and</u><u> </u><u>y</u><u>.</u><u> </u>
- x = 2k = 2 × 36 = 72°
- y = 3k = 3 × 36 = 108°
<u>Therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>right</u><u> </u><u>option</u><u> </u><u>and</u><u> </u><u>small</u><u>est</u><u> </u><u>angl</u><u>e</u><u> </u><u>is</u><u> </u><u>b</u><u>)</u><u> </u><u>7</u><u>2</u><u>°</u><u>.</u>

Step-by-step explanation:
- if u see the diagram, there are 2 triangles in it ABC and ABD.
- the common side for these pair of triangles is AB.
- common angle is angle BAC.
- therefore, these triangles share a common side AB and a common angle BAC.
