Here I am writing theta as A. Because it is difficult for me to write theta always.

Given sinA + cosA = root 2.

On Squaring both sides, we get

(Sin A + cos A)^2 = (root 2)^2

sin^2A + cos^2A + 2sinAcosA = 2

Note: We know that sin 2A = 2sinAcosA

1 + sin2A = 2

sin2A = 1

sin2A = sin90

2A = 90

A = 45.

Hope this helps!
