Question

if one of angle formed by diagonals and adjacent side of rhombus is 20° find all

four angles of rhombus​

Answer 1

Answer:

It is your answer. I hope it's help u

Answer 2

Step-by-step explanation:

since we know that diagonal of a rhombus cut a right angle

therefore let's take angle DOA =90'

and ADO = 20' =OBC =ALTERNATIVE ANGLE

SO WE WILL SUM UP ALL THE ANGLE

ADO+DOA+OAD=180

20+90+OAD =180

OAD=20-90= 70

therefore angle DAB=70+70=140

so DC=CB so angle ODC =20

hence A=140 B=40 C =140 D = 40 have finished
