<u>To solve this problem</u>:
⇒ need to use a special right triangle theorem:
<u>Let's consider the information given</u>:
⇒ one angle is <u>30 degrees</u>
⇒ one angle marked with a little square signifies that it is <u>90 </u>
<u>degrees</u>
⇒ (all the angles added up are 180 degrees) so the last angle is
<u>60 degrees</u>
<u>Therefore we have a '30-60-90' triangle which states</u>:
- the side opposite the 30-degree angle
⇒ half the length of the hypotenuse (longest side of the triangle)
⇒ x = 38/2 = 19
- the side adjacent to the 30-degree angle
⇒ is the square root of 3 divided by 2 of the hypotenuse
⇒ y = 
<u>Therefore</u>:
<u>x = 19</u>
<u>y = </u>
Hope that helps!
