In this math video I (Susanne) explain how to solve an isosceles triangle when the base angles and the area are given. In this geometry problem, we use the tangent function to find the height, then apply the triangle area formula to calculate the length of the base. A clear, step-by-step trigonometry and geometry tutorial perfect for students and exam preparation. Mathematics explained.
