What is the measure of side x in the isosceles triangle that is shown below

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8

If the discriminant if a quadratic equation is 4 which statement describes the roots?
