Question

the of BC OF ∆ABC has been on both sides as shown. if ABD=105° AND ACE=110° THEN find the Angle A​

Answer 1

Answer:

Step-by-step explanation:

B = 180 – 105 (sum of linear pair of angles is 180)

= 75

C = 180 – 110 (sum of linear pair of angles is 180)

= 70

So, A = 180 – (B + C) (sum of angles of triangle is 180)

= 180 – (70 + 75)

= 35 degree
