Extreme road makes an angle of 20° with the horizontal. when the angle of elevation of the sun is 51° a vertical pole beside the road cast a 6 feet long shadow uphill parallel to the road. approximate the length of the pole?

Tan51°=length of a pole/shadow of a pole
Tan51=h/6
H= tan51×6
Now ucan find

(Assumption is made here angle of elevation of a sun is made with horizontal line,not with the road,if it is with the road then u need to add it 51+20=71
Then find tan71,answer may differ)

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.
