Answer:

I think it's 25

Step-by-step explanation:

Because the image next to it has the angles of 90, 65

90+65 = 155

180- 155 =25

It would be 25 degrees because of you put the two triangles together it would form into a rectangle which would make that side a right angle. If the one side is 65 then the other side would be 25 to make 90 degrees
