Are the triangles similar? if so, determine the scale factor of δpqr to δefd. a) no b) yes; 2: 1 c) yes; 4: 5 d) yes; 17: 10

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
