Question

Find x in these 30 - 60 - 90 triangles.

x = ? i will draw the picture

Answer 1

then i also have to find y i am not sure what i am supposed to do on these

Answer 2

Use:

\[\tan(30) = \frac{Opposite}{Adjacent}\]


\[\frac{1}{\sqrt{3}} = \frac{x}{7}\]

Can you find x from it??

Answer 3

okay how did you get 1/square root of 3 = x/7 sorry

Answer 4

\(tan(30) = \frac{1}{\sqrt{3}}\)

Opposite side has length x and adjacent side is given 7..

So,
just put this in the equation above: tan(30) = Opp/Adj
