The answer is A or the first on you might say, hopes this helps ya!
The measure of x will be 18.81 units.
<h3>What are trigonometric identities?</h3>
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
The given information are;
Perpendicular = 4
Base = x
Then, Tan ∅ = Perpendicular /Base
Tan 12 = 4/x
x = 4 /0.212
x = 18.818
Hence, the measure of x will be 18.81 units.
