Question

In the diagram below find the lengths marked x and y. All dimensions are in cm. Answers which are not rational numbers should be given in square-root form.

Answer 1

Cos 60 = x÷2
$\frac{ \sqrt{3} }{2} = \frac{2}{x}$
x = 4 ÷ √3
tan 60= AB÷2(let
let the altitude AB)
√3= ab /2
√3/2=ab
ab is common in both triangles
sin 30 =ab/y
1/2= √3/2y
1=√3/y
y=√3
I hope it works
