Question

In the given figure, Δ ABE - 130 and Δ ACD - 156°. Find BAC
139​

Answer 1

Answer:165 degrees

Step-by-step explanation:

Answer 2

Answer:

Let create a new angels ∠ABC and ∠ACB.

∠ABC  + ∠ABE = 180 (Linear pair)

∠ABC + 139 = 180

∠ABC = 180 - 139

∠ABC = 41

∠ACB + ∠ACD = 180 ( Linear pair )

∠ACB + 156 = 180

∠ACB = 180 - 156

∠ACB = 24

So ,

∠ACB + ∠ABC + ∠BAC = 180 ( sum of all angels of a tringae is 180)

24 + 41 + ∠BAC = 180

∠BAC = 180 - 24 - 41

∠BAC = 180 - 65

∠BAC  = 115
