Answer 1

remember what we said about the angles of a rhombus?

Answer 2

also remember the all the angles add up to 360

and the consecutive angles add up to 180

Answer 3

Ok

Answer 4

and remember, all four sides are equal in a rhombus

Answer 5

Ok

Answer 6

What's the answer

Answer 7

So angle DCA is 30 then what is angle ACB?

Answer 8

Look at that first image I sent

Answer 9

30

Answer 10

Good!

Answer 11

Abc is 10

Answer 12

no, 10 is the SIDE LENGTH

not the angle

Answer 13

Ok

Answer 14

Abc is 10

Answer 15

so to find angle ABC

remember that adjacent angles add up to 180

so

angle DCB is 30 + 30 or 60

so

angle DCB + angle ABC = 180

60 + angle ABC = 180

what is angle ABC = ?

Answer 16

120

Answer 17

yes and remember what we said about opposite angles?

So if angle ABC is 120 then what is angle ADC?

Answer 18

10

Answer 19

I meant 120

Answer 20

Good

Answer 21

now remember that all the sides are equal in a rhombus so if side BC is 10

then that is side DC
