Question 960990

Find {{{BD}}}:

Angle {{{ABC = 90}}} degrees

{{{tan(30) = BD/200}}}

{{{1/sqrt(3) = (BD)/200}}}

{{{BD=200/sqrt(3) }}}...exact

{{{BD=115.47}}} .....approximately

Then,

{{{sin(60) = BD/x}}}

{{{x = BD/sin(60)}}}

{{{x = 115.47/(sqrt(3)/2)}}}

{{{x = 115.47/0.8660}}}

{{{x = 133.3332711666522}}}

{{{x = 133.33}}}....approximately
