Question

3. The diagonals of a rhombus ABCD intersect at O.
If ZDAB = 130° and OA = 8 cm, find the measure of
a) ZABC
b) AC​

Answer 1

the diagonal of triangle ABCD intersect at o if dab =130 and oa=8cm find the measure of abc

consecutive angles of rhombus are supplementary

dab + abc =180

130+ abc =180

abc =180-130

abc =50
