<PRE><B>Question 927900</B>
If the adjacent angles of a parallelogram are in the ratio 2:7 then the smaller of the two angles is of measure a) 50 degree b) 60 degree c) 20 degree d) 40 degree
------------------
The adjacent angles are supplementary.
Equation::
2x + 7x = 180
9x = 180
x = 20
----
2x = 40 degrees
7x = 140 degrees
