Question

3. In the given figure AD and DC are tangents to the circle with centre O .if angle ADE is 20 ° ​

Answer 1

Answer:

The value of AE is 6cm.

Step-by-step explanation:

Consider the provided information.

Perimeter of triangle ABC = 12cm

Perimeter of Triangle ABC = AB + BC + AC

12 = AB + BC + AC

12 = AB + FB + CF + AC

Tangents drawn from an external point to a circle are equal.

BE = FB

Similarly CF = CD

Therefore,

12 = AB + BE + CD+ AC

12 = AE + AD

Tangents drawn from an external point to a circle are equal.

AE = AD

12 = 2 AE

AE = 6

Hence, the value of AE is 6cm.
