Please check my work with these two. The first one I think the answer is √192 but I'm not good with these. With the second one, I think the answer is x = 2.3.  Thank you!

First one  ...this is a  30-60-90 right triangle

The side opposite  the  60° angle will be  √3 * times the side opposite the 30° angle  = √3 * 8  = 8√3  =  √192

So....you were correct....!!!!!!!

 

 

Second one

 

We can use the tangent, here ;

 

tan (20°) = 4 / x         we can rearrange this as

 

x  =  4  / tan(20°)  = 10.99

 

 

cool cool cool
