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....!!!!!!!
We can use the tangent, here ;
tan (20°) = 4 / x we can rearrange this as
x = 4 / tan(20°) = 10.99
