Answer:

A. 16.55

Step-by-step explanation:

What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.

21 * sin(38)

<em>sin(38) calculates to 0.615661475.</em>

21 * 0.615661475

<em>Multiply 21 by 0.615661475</em>

side a = 12.928890975

Now to find x. Use this to find x: √21² - 12.928890975²

√21² - 12.928890975²

<em>Square both numbers</em>

√441 - 167.156221843

<em>Subtract 167.156221843 from 441</em>

√273.843778157

<em>Find the square root of 273.843778157</em>

x ≈ 16.548225831

x ≈ 16.55, so the answer is A.
