Question

In the given figure, prove that LADC =LA+ LB+ LC.​

Answer 1

Answer:

Step-by-step explanation:

let angle ADC be x

The complete angle D is 360 degrees

using angle sum property,

angle A +angle B + angle C + reflex of x(360-x) = 360

angle A + angle B+ angle C +360 = 360 +x

360 cancels and we get the eq.

angle A + angle B+ angle C = x

angle ADC = angle A+ angle B+ angle C.

Hence Proved!
