In this math video I (Susanne) explain how to solve this geometry puzzle. We find the area of the semicircle by using the tangent line and the Sine of the angle in the equilateral triangle (Trigonometry). Mathematics explained.
00:00 Intro – Geometry problem
0:45 Solution
2:51 Angles in a triangle
4:03 Sin Cos Tan
6:18 See you later!
