*SAT QUESTION*

In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is the length of the corresponding side of triangle ABC. What is the value of sinF?

Answer and Explanation:

0.6

Explanation:

Angle F corresponds to Angle C

sinF = sinC

AC² = AB² + BC²

20² = AB² + 16²

AB² = 400 - 256

AB² = 144

AB = 12

sinC = AB/AC

sinC = 12/20

sinF = 0.6

the answer is letter c : ) hope this

answer:

i havent taken the psat, but i have the sat, make sure to bring some snacks, because youre in there forever, 2 sharp number two pencils, an sat approved calculator, and maybe a jacket.   your phone and any books will be taken up, so don't try to bring them(but they will be given back at the end of the testing).   good luck!   i hope you do well!
