Question

ABCD is a rhombus. Find the values of x, y, and z from the figure.

Answer 1

In a rhombus , daignols are opposite to each other and bisect each other

BO=OD=12cm

y=12cm

CO=OA=5cm

x=5cm

since, BC²=CO²+BO², by subtracting value we get

BC²=(12²)+(5²)

BC = root 169

BC = 13cm

since all sides are equal
