Answer:
a. (sec(t)+csc(t))/(1+cot(t)) = sec(t)
Step-by-step explanation:
Subtracting the right side of the equation will result in an expression that is zero for all values of t if the original equation is an identity. That is the case for the equation of (a), but not for the others. See attached.

20 feet
convert yard to foot
1 yard = 3 foot
7 1/3 x 3 = 22
