Question

In the given figure find angle BAC.
​

Answer 1

refer to the attachment

Answer 2

80⁰

Step-by-step explanation:

Total angle = 360⁰

Angle, O = 360⁰-(80⁰+120⁰) = 360⁰-200⁰ = 160⁰

Therefore angle, O = 160⁰

But we need to find <BAC

WE KNOW,

<BAC = <O/2 = 160⁰/2 = 80⁰

Hence,

Angle ,A = 80⁰
