Question

the size z of a rhombus with diameter x and y is given by​

Answer 1

Answer:

z² = (x/2)² + (y/2)²

Step-by-step explanation:

Pythagoras theorem

Answer 2

Answer:

in rhombus Let the point of intersection of the 2 diagonals be x

∴∠AOB=∠BOC=∠COD=∠DOA=90o  ( Property of Rhombus)

In Triangle AOB,

∠AOB+∠OBA+∠BAO=180

90 + x + 40 = 180

x = 180 - 40- 90

x = 50

Similarly, We get y= 50.
