Respuesta :

55 as 90-35=55. The angle marked indicates that the measure of a whole angle must be 90.

Ok here is what I did. I haven't done this since elementary so sorry if it is wrong. I did 180-35 and got 145. Now a way to check is add 35 and 145 and if you get 180 it is correct. Sooooooo 35+145=180!!!!!!!!! I did it!!! Yaa!!!!

Have a great day! Hope this helps.
