To solve this problem:
⇒ need to use a special right triangle theorem:
Let's consider the information given:
⇒ one angle is 30 degrees
⇒ one angle marked with a little square signifies that it is 90
degrees
⇒ (all the angles added up are 180 degrees) so the last angle is
60 degrees
Therefore we have a '30-60-90' triangle which states:
- 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 =
![(√(3) )/(2) *38=19√(3)](https://img.qammunity.org/2023/formulas/mathematics/college/62wx55thj5e2vawhzww9bwdz2zemlkfsfl.png)
Therefore:
x = 19
y =
![19√(3)](https://img.qammunity.org/2023/formulas/mathematics/college/kbp5bu70dnswx7h0mb85ekgcfxe75jo0a4.png)
Hope that helps!
