Question

in the given figure,AC is the diameter of the circle with centre O . if < ADE = 30°,<DAC = 35°,find <ACD​

Answer 1

Step-by-step explanation:

The triangle made by using diameter in a circle makes right angle (90°).

<ADC = 90°

In triangle ADC

<DAC + < ADC + < ACD = 180°

35° + 90° + < ACD = 180°

< ACD = 180° - 90° - 35°

< ACD = 55°
