X =

Answer 1

x = 3

Explanation:

ok then, firstly, lets make line CB into y

sin45 / y = sin 90 / 6
`√(2)`

in other words, as sin 90 = 1

y / sin45 = 6
`√(2)`

y = sin 45 * 6
`√(2)` = 6 as sin 45 = root2/2, and root2 * root 2 = 2, so

6*2/2 = 6

we also know BCD is 30*, as angles in a tri add up to 180*

so, x/sin30 = 6/sin90 = 6

x/sin30 = 6

6*sin30 = x

x = 3 as sin 30 = 1/2
