Explanations not just answers: Sarah measures the angle of elevation to the top of a tree as 23.6 degrees from the point which i
Reika [66]
See the attached diagram.

In the right triangle, x is opposite the 23.6 degree angle, and the adjacent side is 250 m.  This suggests using the tangent ratio.

\frac{x}{250}=\tan 23.6 ^\circ \\ x=250 \cdot \tan 23.6^\circ \approx 109.2

Finally, to get the height of the tree, add Sarah's height, 1.5 m.

The tree is approximately 110.7m tall.

1/2x-9=-25 what is your answer
Elodia [21]
First, let's only the expression with x stay on the let side: let's add 9 to both sides of the equation.

\frac{1}{2} x-9+9=-25+9
which is
\frac{1}{2}x=-16


now, let's multiply everything by 2:

\frac{2}{2} x=-16*2
x=-32


so the answer is -32!
