Can you help me I am completely lost on this question Attachment is below with the question Find the value of each the variable in the figure below

OpenStudy (chayanne):

jhonyy9 (jhonyy9):

what figure is this ,do you know it please ?

OpenStudy (chayanne):

Its a rhombus

OpenStudy (welshfella):

Do you know the property of the diagonals of a rhombus?

jhonyy9 (jhonyy9):

why you think it same ?

jhonyy9 (jhonyy9):

welsh you asked me ? sorry

OpenStudy (welshfella):

No I was asking Chayanne

jhonyy9 (jhonyy9):

ok. yes this is an importantly qustion

jhonyy9 (jhonyy9):

question

OpenStudy (welshfella):

I'l let you have this one jhonny

jhonyy9 (jhonyy9):

chayanne do you know what asked welsh ?

OpenStudy (chayanne):

Is it that opposite sides are congruent

jhonyy9 (jhonyy9):

welsh asked what angle form the diagonales of a rhombus ? or the properties of diagonales of a rhombus

jhonyy9 (jhonyy9):

do you know thet ?

OpenStudy (chayanne):

no, sorry

jhonyy9 (jhonyy9):

so are perpendicularly and halfed - ok. ?

jhonyy9 (jhonyy9):

so what mean that are perpendiculare ,what angle make with how many degree ?

jhonyy9 (jhonyy9):

two lines perpendiculare what angles create ?

OpenStudy (chayanne):

180

jhonyy9 (jhonyy9):

no

jhonyy9 (jhonyy9):

180 degree has a line

OpenStudy (chayanne):

90

jhonyy9 (jhonyy9):

yes exactly

jhonyy9 (jhonyy9):

so than you know that made angles with 90 degree so this mean that 3x=90 yes ? now from this x = ?

jhonyy9 (jhonyy9):

check please your posted image

jhonyy9 (jhonyy9):

so 3x=90 is true ?

OpenStudy (chayanne):

yes because its 90 degree into the angle the rhombus makes

jhonyy9 (jhonyy9):

so than 3x=90 x = ?

OpenStudy (chayanne):

x = 30

jhonyy9 (jhonyy9):

yes nice so now you know that the x has a value equal 30 so than the lateral angle of 2x will be equal by how many ?

jhonyy9 (jhonyy9):

just substitute the 30 in place of x

OpenStudy (chayanne):

Then it would be 60

jhonyy9 (jhonyy9):

yes sure this is easy - yes ?

OpenStudy (chayanne):

Yes, Thank you again

jhonyy9 (jhonyy9):

moment there is again angle y

jhonyy9 (jhonyy9):

hope you know it sure that the sum of angles of a triangle equal how many degree ?

jhonyy9 (jhonyy9):

courage please this is easy

jhonyy9 (jhonyy9):

yes exactly - do you see it that you know - please be more courageosly

OpenStudy (chayanne):

With the angle we know, do we combine the angles we know and then subtract that amount from each side?

OpenStudy (chayanne):

from 180

jhonyy9 (jhonyy9):

sorry i dont understand you from what we subtract but yes we combine ,we assume these angles value what we know so the central angle of 3x has a measure of 90 degree and the lateral angle has 60 degree yes exactly we subtract this sum from 180 do you see it now that is easy ?

jhonyy9 (jhonyy9):

so please calculi it

jhonyy9 (jhonyy9):

how many is the sum of 90 and 60 ?

OpenStudy (chayanne):

So is the final answer for y =30

jhonyy9 (jhonyy9):

yes right,correct so do you understand it now clearly sure ?

OpenStudy (chayanne):

Yes I do now. Thank you so much!

jhonyy9 (jhonyy9):

np was my pleasure and anytime bye bye
