4. A 30-60-90 triangle has a hypotenuse of 16 and a short side of 8. Use special right angle formulas to find the third side. Explain your work. Does your answer match what you got on number 3?

We are given the following right triangle:
The diagram shows a right triangle with a hypotenuse of 16 and a shorter side of 8. The angles are 30 -60 - 90. The shorter side is in front of the smaller angle. We can use the Pythagorean theorem to determine the length of the missing side:
[tex]h^2=a^2+b^2[/tex]Where "h" is the hypotenuse, "a" and "b" are the sides. Substituting we get:
[tex]16^2=8^2+x^2[/tex]Now, we solve the squares:
[tex]256=64+x^2[/tex]now, we subtract 64 from both sides:
[tex]\begin{gathered} 256-64=x^2 \\ 192=x^2 \end{gathered}[/tex]Now, we take the square root to both sides:
[tex]\begin{gathered} \sqrt{192}=x \\ 13.86=x \end{gathered}[/tex]Therefore, the value of the missing side is 13.86
