This question i don’t understand it difficult

I'm not entirely sure, but if the measure of both A and D are 55, then the answer for F would be 35. The angles didn't grow, but the sides of the two triangles did. Both of them still have 90 degree angles, and if angles A and D have 55, then angle F would match angle C and the answer would be 35. In a triangle, the angles will always add up to 180, so 90 plus 55 is 145 and so the last angle would have to be 35.

what class or school are you in i may
