Question

ABCD is a rectangle and diagonals intersect at O. If angle AOB= 118 find angle ABO
​

Answer 1

Step-by-step explanation:

Given=ABCD is a rectangle, diagonals intersect at O

Find=<ABO

solve=<AOB=118°

<AOB+<OBA+<OAB=180° (sum of angle of∆)

118°+<OBA+<OBA=180° (<OBA=<OBA, because

opposite side are

equal)

2<OBA=180°-118°

<OBA = 62°\2

<OBA=31°

<AOB is 31°
