Answer

22\sqrt{2}

Step-by-step explanation:

First we gave a name to the side that is common for both triangles, can be Y for example.

Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.

sin(45)=\frac{11}{Y}  \\ , Because sin(x)= op/hip

cos(60)=\frac{Y}{x} , Because con(x)=ad/hip

Having this equations, we can solve the system and find x

Y=\frac{11}{sin(45)} \\Y=cos(60)*x

we equal Y and solve

\frac{11}{sin(45)}=cos(60)*x\\ x=\frac{11}{sin(45)*cos(60)} \\x=\frac{11}{\frac{\sqrt{2} }{2} *\frac{1}{2} } \\x=\frac{11}{\frac{\sqrt{2} }{4} } \\x=\frac{44}{\sqrt{2} }\\

Then we rationalize

x=22\sqrt{2}

Hope you like it!

Answer:

● \displaystyle 1

Step-by-step explanation:

According to the Definition of Rational Exponents [part I], you can rewrite radicals as exponents:

\displaystyle a^{\frac{m}{n}} = \sqrt[n]{a}^m \\ \\ \sqrt{y^2} = y, where\:any\:invisible\:exponent\:is\:ALWAYS\:1
