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!

#1**+2 **

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
