Question

if abcd is rhombus and digonals ac and bd intersect at o if angle oab =55​

Answer 1

Answer:

angle OAB =55°

angle DAB = 55*2=110° [diagonals of rhombus bisect the vertex angles]

angle DAB = angle DAB =110° [properties of a parallelogram as rhombus is a parallelogram]

angle ABC = 180- angle DAB= 180-110=70°

Angle ADC= angle ABC =70°
