Question

plz answer this question​

Answer 1

Answer:

ACD=180-110. staright line angle is 180°

=70

triangle ACD

ACD+CAD+ ADC=180°

50+70+ADC=180°

ADC=60

In triangle DAB

angle D+ angle A+ angle B=180

40+60+BAD=180

BAD=100°

BAE is staright line

so angle BAD+DAE=180

100+DAE=180

DAE=70

Answer 2

(i) <ACD = 70°

(ii) <ADC = 60°

(iii) <DAE = 30°

(i) <ACD :

180-110=50°

(ii) <ADC :

Let angle ADC be d

50+70+d=180

d=60°

(iii) <DAE :

Let the angke DAE be a

40+110+a=180

a=30°
