Question

In figure is shown AC and BC are two tangents to the circle O
with radius is 5 cm. If OC=13 cm
& OD; DC = 3:10, them what is
ethe perimeter of triangle ABC ?​

Answer 1

Answer:

In the given figure, AC and BC are two tangents to the circle which center 0 and radius

5 cm. if OC=13cm and OD:DC=3:10, then find the perimeter of triangle ABC.

Step-by-step explanaTtion

Given AE=5cm

Perimeter of triangleABC=AB+BC+CA

                                    =AE−BE+AD−CD+BF+CF

         As it is seen from the figure

              CD=CF,BE=BF (properties of tangent of circles)

                                       =AE+AD (as AE=AD)

                                        =5+5=10cm

Answer 2

Answer:

given AE =5cmhbbcfftuj
