(We omit the "inner circle" of the tire for clarity.) We can use the basic facts of angles to redraw this situation in a more familiar form.

Now, we want to find the height of the mark above the ground.

(Don't estimate until the very end.) From the diagram, $tan30^\circ$ = $\frac$ where x denotes the distance (in meters) from the closer viewing point to the wall.

also, $tan50^\circ$ = $\frac$ we get, $x 45=\frac$ $x=\frac.$ subtracting the equations, we get, $45= h\left(\frac1-\frac1\right).$ You're done!!

I look at the right triangle as two separate triangles.

First I used law of sines on the triangle to the left to find the hypotenuse of the whole right triangle, the distance from the 30Deg measurement to the top of the tower. Of course they all have to add up to 180 degrees: 0-50=130$0 30=160$ 0-160=20$https://me/c604326/v604326834/130f9/VZT0a I now have all the angles for the triangle on the left to find the hypotenuse. hypotenuse = m(\sin(130\deg)/sin(30\deg))= 100.7893$ To find the proportion of the adjacent to the hypotenuse (which we already know and can just multiply the value), we use cosine.

This tutorial offers advice on how to solve trigonometric problems and provides several problems worked through in detail. If an explanation / walkthrough is not clear, please let me know in a comment and I will try to improve the answer.

But before we delve further into this relationship, we must first define some properties of the angle is also equivalent to 360°. One radian is defined as the angle formed such that the portion of the circle (or arc length ) swept by that angle is equal to the radius of the circle.

Thus, logically, we expect trigonometry to have a role in our understanding of circles as well as right triangles.
