Question

In the adjoining figure, ABC is a right angled triangle in which angle ABC=90° and AB=6 cm.D is a point on BC produced such that angle ADB= 30° . Find CD.​

Answer 1

Step-by-step explanation:

angleBAC = angle ACB = 45

= AB= BC= 6cm

(AC) ^2 = (AB)^2 + (BC)^2 [Pythagoras]

AC= root72

also, angleACB + angleACD= 180 (Linear Pair)

so, angle6= 95degree

angleCAD= 55degree (Angle sum property)
