this is answer
question 5 (i) =m angle B =60 C =65
(ii)=m angle D=30 F=90
question 6 m angle A=60 c=30


give me steps
pleasssssss
for class 7th
ok​

Answer 1

Answer:

5.(i)angle A=55°,C=65°

Outer angle C=Inner angle C(due to vertically opposite angle)

angle C=65°=>angle B=180°-(A+C)=180°-120°=60°

=>angle B=60° and angle C=65° .

(ii)You know,an outer angle equals to the sum of two far angle.

=>F+E=D=>F=D-E=150°-60°=90°

And now,E+F+inner angle D=180°=>inner angle D=180°-(E+F)=180°-150°=30°

=>angle D=30° and angle F=90° .

6.Inner angle C= Outer angle C(as same as question no.5(i))

and,angle A=180°-(90°+30°)=60°

=>angle A=60° and angle C=30° .
