Question

plz solve both sums

Answer 1

d)
PST IS AΔ TRIANGLE
= p + s+t = 180 (angle sum property)
=90 +x+y = 180
= x +y = 180-90
=x+y = 90
so
x = 90-y
and
y=90-x


HOPE IT WILL HELP U

Answer 2

x=10
y=80
you can add angle PQR+anglePRQand subs from 180
then QPR=100
question says that PT is bisector of angle QPR.Then RPT=50and SPQ=50
then anglePSQ+anglePQS and then subs from 180 then angleQPS=40 . Then subs TPQ -SPQ=SPT that is x and then add all angleTPS+TSP=SPT that is y
