Question

Please help my exam is on this tomorrow

Answer 1

Do you see the right triangle in the picture ?

The TANGENT of angle-x is 10m/17.3m. Do the division, find that number, then use your calculator or search online to find the angle that has that number for its tangent.

I get roughly 30 degrees, but you should check me.

Answer 2

We know that :

$Tan\theta = \frac{Opposite\;Side}{Adjacent\;Side}$

From the Figure :

$Tanx = \frac{Height\;of\;the\;Tree}{Shadow\;of\;the\;Tree}$

Given : Height of the Tree = 10 m

            Length of its Shadow = 17.3 m

⇒ $Tanx = \frac{10}{17.3} = 0.578$

⇒ $x = Tan^-^1(0.578)$

⇒ x° = 30°
