✌Rpta: El valor de la expresion A es 1

[tex]\boldsymbol {\mathsf {Procedimiento}}[/tex]

Debemos recordar las Razones trigonometricas de los angulos notables

• sen (30°) = 1/2
• tan (37°) = 3/4

Ahora el ejercicio

[tex]\begin {gathered}\mathsf {A = sen^{2} (30^{o}) + tan (37^{o})}\end {gathered}[/tex]

[tex]\begin {gathered}\mathsf {A = (\frac {1}{2})^{2}+ \frac{3}{4}}\end {gathered}[/tex]

[tex]\begin {gathered}\mathsf {A = \frac {1}{4}+ \frac{3}{4}}\end {gathered}[/tex]

[tex]\begin {gathered}\mathsf {A = \frac{4}{4}}\end {gathered}[/tex]

[tex]\begin {gathered}\mathsf {A = 1}\end {gathered}[/tex]

Te adjunto una tabla de las razones trigonometricas de los angulos notables

Atentamente: [tex]\begin {gathered}\mathsf{\boxed{\bold {E}}_{\boxed {\bold {N}}}}\end {gathered}[/tex][tex]\begin {gathered}\mathsf{\boxed{\bold {V}}_{\boxed {\bold {E}}}}\end {gathered}[/tex][tex]\mathsf{\boxed {\bold{R}}}[/tex]
