Answer 1

Respuesta:

b = 23.82 ;  θ = 35.82  ;  α = 54.18

Explicación paso a paso:

Aplicamos Teorema de Pitágoras

$b^{2} =a^{2} +c^{2}$

$b^{2} =15^{2} +18.5^{2}$

$b^{2} =225 +342.25$

$b=\sqrt{567.25}$

$b=23.82$

Calculamos "$\alpha$"

$sen\alpha =\frac{15}{18.5}$

$\alpha =sen^{-1} \frac{15}{18.5}$

$\alpha =54.18$

Calculamos θ

$\alpha +$ θ = 90

54.18 + θ = 90

θ = 90 - 54.18

θ = 35.82
