Question

The answer of this question in the picture

Answer 1

see explanation

Explanation:

Note that

sin60° =
`(√(3) )/(2)`, cos60° =
`(1)/(2)`

Using trig. ratios in the right triangle

sin60° =
`(opp)/(hyp)` =
`(x)/(18)` =
`(√(3) )/(2)` ( cross- multiply )

2x = 18
`√(3)` ( divide both sides by 2)

x =
`(18√(3) )/(2)` = 9
`√(3)`

-----------------------------------------------------------------------------

cos60° =
`(adj)/(hyp)` =
`(y)/(18)` =
`(1)/(2)` ( cross- multiply )

2y = 18 ( divide both sides by 2 )

y = 9
