In triangle QTR,
QTR + TQR + X = 180 (Angle Sum Property)
90 + 40 + x = 180
x = 180 - 130 = 50
In triangle PSR,
PSR + SPR + PRS = 180 ( Angle Sum Property)
50 + 30 + PSR = 180
PSR = 180 - 80 = 100
y + PSR = 180 ( Linear Angles)
Y = 180 - 100 = 80
QTR + TQR + X = 180 (Angle Sum Property)
90 + 40 + x = 180
x = 180 - 130 = 50
In triangle PSR,
PSR + SPR + PRS = 180 ( Angle Sum Property)
50 + 30 + PSR = 180
PSR = 180 - 80 = 100
y + PSR = 180 ( Linear Angles)
Y = 180 - 100 = 80
is it correct
are u confirm
or it could be done by exterior angle property if u doubt
it is totally comfirmed
ok
thanks a lot
No problem
