Given the triangle number 7:
As shown, there is a right angle triangle
The hypotenuse of the triangle = x
The opposite side to the angle 63 = 16
Using the sine function to find x as follows:
[tex]\begin{gathered} \sin 63=\frac{opposite}{hypotenuse} \\ \\ \sin 63=\frac{16}{x} \\ \\ x=\frac{16}{\sin 63}=17.957 \end{gathered}[/tex]
Rounding the answer to the nearest tenth
So, the answer will be x = 18
