Yes, they are similar. The definition of similar triangles is two triangles that have congruent angles. All angles of a triangle must add up to 180. So, if you take the angles that you already have and add them up (17 plus 17 = 34), Then there is only one option of what the last angle is. To find the last angle you take 180 and subtract 34 which would give you 146.
