In triangle ABC, the measure of angle B is 90 degrees, BC=80 and AC=100. Triangle DEF is similar to ABC where vertices D, E, and F correspond with vertices A, B, C. The scale factor of DEF to ABC...

(18n2-9n+1)/(3n-1)

angle x may equal... 1. 0 2. 30 3. 45 4. 150

solve the difference equation x_{n+2} - 4x_{n}= n with initial conditions: x_{0} = 0, x_{1} = 1/3

This is a trig question.
