Question

how angle ADC is greater than angle ABD In this solution ​

Answer 1

Answer:

angle ADC is greater than angle ADB because it is the exterior of triangle ADC.

Answer 2

Answer:

if it is a equilateral triangle,as we know three angles of sum is 180 degree,then BAC is divided mean 60÷2=30

then BAD+ABD =90 degree and ACD+DAC=90degree ,as we know ADC+ACD+DAC=180

SO WE GET ADC =90degree

and ABD =60 degree
