a triangle is equal to 180 degrees. we know that one of the angles is 118 and the other is 30 degrees. now we have a total of 148 degrees. so that means the other angle is 32 degrees. and both triangles are identical so that means
x= 32
so what i did you get 148 is i added 118 and 30 together and then i subtracted 118 from 180 to get 32
i hope this helps
