To answer these you must know Soh Cah Toa

Sin = opp/hyp
Cos = adj/hyp
Tan = opp/adj

I’ll do #23 for you.
x = the angle
Tan (x) = 8/6 (8 is opp of ang and 6 is adj)
Then you must do the inverse
x = tan^-1 (8/6)
Then use a calculator to solve for x.
Use this system for the rest of the problems (won’t necessarily be the tangent)

Find the limit, if it exists. (if an answer does not exist, enter dne.) lim x → ∞ x4 x8 + 2
tatyana61 [14]

lim x → ∞ x^4 x^8 + 2

Combine exponents:

lim x → ∞ x^(4 +8) + 2

lim x → ∞ x^12 + 2

The limit at infinity of a polynomial, when the leading coefficient is positive is infinity.
