Question

if angle DAC= 30 degree find the angles of triangle ABC

Answer 1

assuming that dac is a right angle , angle dac= 30° , angle ADC= 90° ACD= 60°

Answer 2

Answer:

Question is not proper  

Assume triangle DAC is a right angled triangle  

Then angle CDA = 90

Sum of the angles in a triangle are 180

Therefore, $\angle DAC + \angle CDA + \angle ADC = 180^{o}$

       $30 + 90 + \angle ADC = 180^{o}$

$\angle ADC = 180-30-90 = 60^{o}$

$\angle ADC = 60^{o}$
