ABCD us a rectangle. Find the values of x and y in each case.
figure is like this
AB is base and angle A is 35 degree
DC is opposite site
AC and BD is diagonal and intersent on O in mid pint and DOC is formed Y degree and BOC is formed X degree
As diagonals of a rectangle bisect each other and are equal,
∴AO = BO
⇒∠OAB = ∠OBA = 350
In ΔOAB,
∠OAB + ∠OBA + y = 1800
⇒ 350 + 350 + y = 1800
∴y = 1100
x + y = 1800
∴x = 1800 - y = 700
