Answer 2

Answer:

x= 60°

y= 45°

Step-by-step explanation:

AC is a diameter

so

Angle ABC =90°

In ∆ ABC

angle ABC + Angle ACB + angle BAC = 180°

90°+ angle ACB + 30°=180°

angle ACB = 180° - 120°

= 60°

x= 60°

In ∆ADC

angle ADC= 90° ( beacuse AC is a diameter)

since,

AD=DC ( if two sides are equal then opposite angle are also equal)

Angle DAC= Angle DCA= 45°

y=45°
