Question

Page No. Date 2 In the adjacent A ABC beg AD ABC beg AD I seg B, LC = 45°, BD AC=8 52 then find AD and BC

​

Answer 1

Step-by-step explanation:

given AD is perpendicular to BC

=> ZD = 90°

now consider Ale ADC

here ZD is 90° and ZC is 45°

sum of angles equals to 180° so, ZA = 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

=> (8v2) = 2DC? => 128/2 = DC

=> DC = 8 =AD

so AD = 8 then

BC BD + DC

=> BC = 13
