Question

In the given figure, show that : angle a = angle b + angle c
(i)if angle b =60° and angle c=50° find angle a
(ii) if angle a=100° and b=55° find angle c
(iii)if angle a =108° and angle c =48° find angle b.

(please give the answer fast.
thank you)​

Answer 1

(1) angle a= 110°

(2) angle c =45°

(3) angle b = 60°

Step-by-step explanation:

(1) angle a = angle b +angle c

angle a= 60°+50°

angle a=110°

(2) angle a= angle b +angle c

100° = 55° + angle c

100° -55° =angle c

45° = angle c

(3) angle a= angle b +angle c

108° =angle b + 48°

108°- 48° = angle b

60° = angle b
