What are the values of x and y in the diagram? A. x = 68° y = 121° B. x = 78° y = 121° C. x = 78° y = 111° D. x = 68° y = 111°

here is the pic

ganeshie8 (ganeshie8):

first find \(y\)

OpenStudy (anonymous):

how

ganeshie8 (ganeshie8):

use below : sum of angles in quadrilateral = 360

ganeshie8 (ganeshie8):

y + 62 + 84 + 103 = 360 solve y

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

then what

ganeshie8 (ganeshie8):

wat do u get after solving ?

OpenStudy (anonymous):

599

ganeshie8 (ganeshie8):

to solve something, u just need to isolate it

OpenStudy (anonymous):

this is so hard

ganeshie8 (ganeshie8):

y + 62 + 84 + 103 = 360 y + 249 = 360

ganeshie8 (ganeshie8):

subtract 249 both sides

ganeshie8 (ganeshie8):

y + 249 = 360 - 249 -249

ganeshie8 (ganeshie8):

y = ?

OpenStudy (anonymous):

can u just give me the soulution becuease i am getting confused.. please

ganeshie8 (ganeshie8):

subtract 360-249 y = 111

ganeshie8 (ganeshie8):

you still need to find x

ganeshie8 (ganeshie8):

u have 50-50 chances... if u dont wanto work it :P

OpenStudy (anonymous):

ok

ganeshie8 (ganeshie8):

lol wat ok, use below to solve x : sum of angles inside a triangle = 180

ganeshie8 (ganeshie8):

x + 36 + 76 = 180 see if u can solve x
