The Seattle Space Needle casts a 67-meter shadow. If the angle of elevation from the tip of the shadow to the top of the Space Needle is 70º, how tall is the Space Needle? Round to the nearest meter.
We can use the tangent here
tan 70° = height of needle / length of shadow
tan 70° = h / 67 rearrange as
67 * tan 70° = h ≈ 184 m
