Answer» AD = 8 and BC = 13 Step-by-step explanation: given AD is perpendicular to BC => ∠D = 90° now consider Δle ADC here ∠D is 90° and ∠C is 45° sum of angles equals to 180° so, ∠A = 45° when TWO angles are EQUAL it is a ISOSCELES TRIANGLE in which two sides are also equal so AD = DC hypotenuse theorem, AC² = DC² + AD² => (8√2)² = 2DC² => 128/2 = DC² => DC = 8 =AD so AD = 8 then BC = BD + DC => BC = 13 |
