Answer 1

Answer:

Step-by-step explanation:

Now we have PQ=PR & thus we can take PT as a bisector. Now we can take ∠QPT=∠PTS as they are Alternate Interior Angles.

So now we can do ∠PTS+∠STR=90. So by putting the values we can take:

               50+y=90

                      y=90-50

                      y= 40
