Answer:
tan2(x) + 1 = sin2(x)/cos2(x) + 1 = [sin2(x) + cos2(x)]/cos2(x) = 1/cos2(x) = (1/cos(x))2 = sec2(x). Thus tan2(x) + 1 = sec2(x).
Step-by-step explanation:
In order to know the degree of the polynomial of a given expression, look for the variable having the largest exponent. So in the given polynomial above, the largest exponent is 8. Therefore, the polynomial has a degree of 8. So the answer would be option C. Hope this answer helps.

Use trigonometry. You will use cosine. make sure calculator is in degrees.
cos(22)=x/11
.927=x/11
X=10.199
