Sagot :
If we match up the triangles, angle A will be equal to angle D , D is equal to [tex]{ 38 }^{ o }[/tex] since this is a right triangle the other angle is 90 degrees we should add this two and substract their total from 180.
[tex]90+38=128\\ 180-128=52\\ [/tex] the answer must be D
[tex]90+38=128\\ 180-128=52\\ [/tex] the answer must be D
