Question

ABCD is a rhombus of perimeter 16cm. if it's one side AB and a diagonal AC are(3x+1)cm each then find x and angleADC and angleDAB.

answer; x=1
angleADC=60°
angleDAB=120°​

Answer 1

Step-by-step explanation:

all sides are equal in rhombus

p=16

let side=s

4s=16

s=4

AB=AC

3x+1=4=>x=1

ADC is a equilateral triangle

therefore angle ADC=60

DCparallel toAB

angleADC+angleDAB=180

60+angleDAB=180

angleDAB=120

Answer 2

Answer:

ANGLE ADC IS 60° AND ANGLE DAB IS EQUAL TO 120°《▪︎》▪︎》●》●■○♤ JSBEGDJQK
