(1- cos10° + cos40° - cos50°)/(1 + cos10° - cos40°-cos50°) == tan 5º. cot 20°

X^4 + 36x^2 = x^2(x^2+36)= x*x*(x+6i)(x-6i) mark me brainliest

Check the internet ok that will

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.
