Question

Find the missing side lengths

I need help in y = ( it's not 6 I put every number and still got it wrong)​

Answer 1

y = 9√3

x = 18

Explanation:

taking 30 as reference angle

b = y

p = 9

h = x

so

tan30 = p/b

1/√3 = 9/b

or, b = 9√3

so

`h^2 = p^2 + b^2\\x^2 = 9^2 + y^2\\or, x^2 = 81 + (9√(3) )^2\\or, x^2 = 81 + 243\\or, x ^2 = 324\\or, x =√(324) \\\\so x = 18`
