Answer 1

Answer:

x=30°,y=60°,z=90°

Angle DCX= Angle ADC+AngleDAC. [ In triangle exterior angle is equal to sum of the opposite interior angle ]

120°=X+90°

X°=120°-90°

X°=30°

In ∆ ADC [angle sum property]

90°+X°+Y°=180°

90°+30°+Y°=180°

Y°=180°-120°

Y°=60°

Now In ∆ ABC

X°+Y°+Z°=180°

30°+60°+Z°=180°

Z°=180°-90°

Z°=90°
