Since the 90 degree angle is on a straight line, the one attached to it is also going to be 90 degrees and in one triangle the Desiree’s must add up to 180 so we are given 90 and 23 on one side so the other angle is going to be 67 which is attached to the other angle and therefore when u do 180-90-67 for the unknown x triangle u should get 23
