Ans : a - 40 degree

Let angle T be x . Thus angle R= x+10
Some of all the sides of the traingle is 180 degree

GOing by this , x+x+10+90 = 180 degree . Thus x=40 degree

Thus x = 40 degree

R = T +10

and S+R+T = 180

We know S = 90

Hence, the above equations we get T = 40

Answer = A

1. The remaining angles should be 90 degree.
2. So, R + T should be 90 degree.
3. Since R = 10 + T, so (10+T) + T = 90, thus T = 40 (and R is 50).
