Question

Razones trigonometrícas

C=TG45°+SEN30+2
​

Answer 1

C = Tan45° + Sen30° + 2

Recordando los valores de las razones trigonometeicas, sabemos que :

Tan45° = 1 ; Sen30° = 1/2

Reemplaza :

C = 1 + 1/2 + 2

convertimos en fracciones homogeneas :

C = (1×2)/(1×2) + 1/2 + (2×2)/(1×2)

C = 2/2 + 1/2 + 4/2

C = ( 2+1+4)/2

C = 7/2
