In the given figure if the angle between A and − C is 5 α ∘ , find the value of α .

From the figure, the angle between A and C is 7 5 ∘ + 6 0 ∘ = 13 5 ∘ . Angle between A and − C is 18 0 ∘ − 13 5 ∘ = 4 5 ∘ . So 5 α = 45 ⇒ α = 3 .

Answer:

Solution:

From the figure, the angle between $A$ and $C$ is $7 5^{\circ} + 6 0^{\circ} = 13 5^{\circ}$ .

Angle between $A$ and $- C$ is $18 0^{\circ} - 13 5^{\circ} = 4 5^{\circ}$ .

So $5 α = 45 \Rightarrow α = 3$ .
