Question

the adjacent side of rombus are (4×-5) and (2x+15) find the length of its sides ​

Answer 1

Answer:

all sides of rhombus are equal

4x - 5 = 2x + 15

4x - 2x = 15 + 5

2x = 20

x = 10

lenght of side 1 = 4x - 5 = 35

lenght of side2 = 2x = 15 = 35

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Step-by-step explanation:

as the adjacent sides=(4x-5)

=(2x+15)

thus rhombus all sides are equal

thus, 4x-5=2x+15

4x-2x=15+5

2x=20

x=10

adjacent side =4x-5

4×10-5

=35
