I think it may be a 180 degree angle but I wouldnt trust myself so idk
4 : 8
x 9 => 36 : 72 <=== equivalent
never going to left you go
never going to left you down
Photo-math take a picture of your problem and it will give you your answer
X=60degrees
bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.
Hope this helps.
