Question

With the same data ($\angle C = 90^\circ$, $AB = 29$, $BC = 21$, $\angle ABC = 	heta$), $\cos	heta = ?$

Accepted Answer

$\dfrac{21}{29}$

Answer

$\dfrac{20}{29}$

Answer

$\dfrac{21}{20}$

Answer

$\dfrac{20}{21}$

With the same data (∠C=90∘\angle C = 90^\circ∠C=90∘, AB=29AB = 29AB=29, BC=21BC = 21BC=21, ∠ABC=θ\angle ABC = \theta∠ABC=θ), cos⁡θ=?\cos\theta = ?cosθ=?
