Question

I found the sides of the triangle but I need the answer. Sides are:

RS=√125
ST=5
RT=10

Answer 1

It will be a right triangle
RS=squareroot125
RS^2=125
now RT^2+ST^2=5^2+10^2ī
=25+100
=125
since RT^2+ST^2=RS^2
according to pythagoras therom it is satisfied
so it is right angle at T

Answer 2

This should be a right triangle because it follows the Pythagorean theorem:
a^2 + b^2 = c^2

5*5 + 10*10 = (√125)^2
125=125
