Question

Does anyone know how to solve this and whats the answer?

Answer 1

you can use the interior angles postulate for triangles
So what that means is that the interior angles of a triangle will all all up to 180 degrees
since we know d=t (the angles) we can assume that a=44, t=39
so then we add those, 39+44=83, so then c=180-83
180-83=97, so c=97
Then, since the triangles are similar, c=r, so r=97 degrees :)

Thanks Alot ill let you know if I get ti right
