Question

in adjoining figure rhombus, angle A=60
ab=3x+2
ad=4x-4
bd=y-1
find x and y

Answer 1

Step-by-step explanation:

ab = 3x + 2 = ad = 4x -4

all sides of rhombus are equal

3x + 2 = 4x - 4

4x - 3x = 4 + 2

x = 6

ab = 3x 6 + 2 = 20

BD = 20 = y - 1

20 = y - 1

y = 21

so answer is x = 6 , y = 21

Answer 2

∴4x−4=3x+2

x=6

side AD=DC,

∠DAC=∠DCA=60

0

y−1=20,

y=21 units
