Question

Q.15. In AABC, ZAis 70° and AD is perpendicular to BC. If ZC
= 50°, find ZDAC and ZABC.
​

Answer 1

Answer:

ZDAC=180-(90+50)=40 DEGREE

ZBAD=70-40=30

=ZABC=180-(30+90)=60

Answer 2

Answer:

angle dac

50+90+dac=180

dac=180-140

dac=40

a= 70

dac+dab=70

40+dab=70

dab=50

a+b+d=180

50+b+90=180

abc=40
