English

In Right-angled Triangle Abc; B = 90°. Find the Magnitude of Angle A, If: Ab is √ 3 Times of Bc.

In right-angled triangle ABC; ∠ B = 90°. Find the magnitude of angle A, if: AB is √3 times of BC.

Sum

Consider the figure

Here AB is `sqrt(3)` times of BC means

`"AB"/"BC" = sqrt(3)`

cot θ = cot 30°

θ = 30°
