Question

Two adjacent angle of a rhombus are in the ratio 4:5.Find all the angle of the rhombus​

Answer 1

Answer:

Let the rhombus be ABCD

Let the common multiple be x

4x and 5x

4x+5x=l80 (adjacent angle of a rhombus)

9x=180

x=180/9

x=20

4x=4(20)

=4×20

=80

5x=5(20)

=5×20

=100

A=C (Opposite angles of a rhombus)

B=D ( same as above)
