You need to state more info, this isn't even a question

AAS(angle-angle-side), SSS(side-side-side), SAS(side-angle-side), ASA(angle-side-angle), and HL(hypotenuse-length)
4 1/4 is equivalent to 4.25 so you can just multiply 4.25*8 and you'll get 34 which is c.
Triangle ABC is similar to triangle DEF because all triangles have 180 degrees. When you subtract 180 by 30, you get 150. When you subtract 150 by 6<span>4</span>, you get 86. Therefore, the triangles are the same.
