Question

find : x + y+ z????????????????

Answer 1

here is ur answer>>
***the value of x will be 180 degree minus 50 degree which is equal to 130 degree the value of Y is 90 degree 180 degree minus 90 degrees 90 degrees the value of Z is 140 degree 180 degree minus 40 degree equals 140 degree therefore X + Y + Z is equal to 130 degree + 90 degree + 140 degree which is equal to 360 degree also we could calculate this using exterior angle property of triangle formula the sum of exterior angle of a triangle is always 360 degree
hope this helps!!!!**

Answer 2

$x + 50 = 180 \: \: \: \: (linear \: pair) \\ x = 180 - 50 \\ x = 130 \\ \\ angle \: sum \: property \\ 50 + 40 + z = 180 \\ 90 + z = 180 \\ \\ z = 180 - 90 \\ z = 90 \\ \\ 90 + y = 180 \: \: \: (linear \: pair) \\ y = 180 - 90 \\ y = 90 \\ k = 130 \: \: \:( vertically \: opposite \: angle) \\ k + z = 180 \: \: (co \: interior \: angle) \\ 130 + z = 180 \\ z = 180 - 130 \\ z = 50 \\ \\ \\ \\ hope \: it \: help \: you \\ \\ please \: mark \: brainiest$
